What are the step to the Quadratic Formula?

Mathematics
1 answer:

The steps to solve a quadratic formula include:

  • Combine all of the like terms and move them to one side of the equation
  • Factor the expression
  • Set each set of parenthesis equal to zero as separate equations
  • Solve each "zeroed" equation independently

<h3>What is a quadratic equation?</h3>

In algebra, a quadratic equation is a equation that can be rearranged in standard form as where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0.

A quadratic equation is an equation that could be written as ax² + bx + c = 0

when a 0. The factoring method is illustrated:

To solve a quadratic equation by factoring, put all terms on one side of the equal sign, leaving zero on the other side.

Set each factor equal to zero.

Solve each of these equations.

Check by inserting your answer in the original equation.

Example 1

Solve x² – 6 x = 16.

Following the steps,

x² – 6 x = 16 becomes x² – 8x + 2x – 16 = 0

Factor.

( x – 8)( x + 2) = 0

Therefore, x = 8 and -2.

Question 374756: Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels
Dvinal [7]

Let the number of hours = X

Multiply the speed of each train by the number of hours (x) and add them together to equal the total miles:

75x + 95x = 238

Simplify:

170x = 238

Divide both sides by 170:

x = 238/170

x = 1.4 hours.

Check:

75 x 1.4 = 105 miles

95 x 1.4 = 133 miles

105 + 133 = 238 miles

It will take 1.4 hours ( 1 hour and 24 minutes).

Bob and will toss two coins. if both coins come up heads, bob pays will $6. will pays bob $2 otherwise. what is the expected val
Helga [31]
Each coin has a head and a tail, therefore when you toss two coins, you have 4 possible outcomes. You have two heads in only one of these outcomes, while the other three have at least one tail.

The expected value of the game is the price paid/gained times the probability of loss/victory:

E = (1 / 4) · (-6) + (3 / 4) · (2)
   = -3 / 2 + 3 / 2
   = 0

Bob expects to tie with Will.

What is the length of side a? Round to the nearest tenth of an inch. Enter your answer in the box. ( Answer in Inches )
Jet001 [13]

Given:

Base of a right triangle = 7 in

Height of a right triangle = a

Hypotenuse = 16 in

To find:

The length of side a.

Solution:

Using Pythagoras theorem:

\text{Base}^2+\text{Height}^2=\text{Hypotenuse}^2

7^{2}+a^{2}=16^{2}

49+a^{2}=256

Subtract 49 from both sides.

49+a^{2}-49=256-49

a^{2}=207

Taking square root on both sides, we get

a = 14.4

The length of side a is 14.4 in.

What are all the names to a polygon that has 2 pairs of parallel sides 2 pairs of sides equal in length and 2 acute and 2 obtuse
tester [92]

Answer:

a trapezoid

Step-by-step explanation:

A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs

Characteristics of a trapezoid

It has 4 vertices and edges

If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram

Area of a trapezoid =   x (sum of the lengths of the parallel sides) x height

Perimeter =  sum of lengths of sides of a trapezoid
