What are the step to the Quadratic Formula?

Mathematics

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.

Please look at number 10. from the slope and write the equation for me
kompoz [17]

Answer:

y = 8x + 38

Step-by-step explanation:

To find the slope we set up y = mx + b and plug m (our slope) in and then plug in the point into x and y to find b (our y-intercept)

   y = mx + b

   y = 8x + b

   6 = 8(-4) + b

   6 = -32 + b

+32   +32

 38 = b

So using our slope and our intercept we have our slope intercept

y = mx + b

y = 8x + 38

Hope this helps :)

Hello everyone I need help with this worksheet it's ten problems answer the ones you know for me please it's homework.
Fed [463]

Answer:

1. Slope = -4/5

2. Slope = 2/3

3. Slope = 0

4. Slope = 3/-4

5. Slope = 7/-12

6. Slope = 1/2

7. Slope = -2/0 --> Undefined

8. Slope = 3/-2

9. Slope = 5/-4

10. Slope = 4/3

Step-by-step explanation:

Ok so I'm assuming that you want the slope for all the two points. Basically, the formula for slope is rise/run, or y2-y1/x2-x1. Solve using that. For example, for number 1, it would be:

10-2/1-11 = 8/-10 = -4/5

Step-by-step explanation:

Plan A costs 419.88 dollars per year  (34.99*12= 419.88)

Plan B costs 539.88 dollars per year (134.97 * 4 = 539.88)

PLEASE ANSWERRRRRRRRRRRRRRRRR
zhannawk [14.2K]

The graph suggests that the two lines meet at (3,6)

If this is true, that point must belong to both lines.

To check this, plug x=3 in both equations, and you must get y=6 once you simplifiy all the numbers.

In the first equation we have

5\cdot 3-3y= -3 \iff 3y=15+3\iff 3y=18 \iff y=6

In the second,

3+3y=21 \iff 3y=18\iff y=6
