Factoring Trinomials in Standard form x^2+2x=-1

Mathematics
1 answer:
Paul [167]3 years ago
3 0

Answer:

(x + 1)(x + 1) = 0  OR  (x + 1)^2 = 0

Step-by-step explanation:

First, we need to get the trinomial x^2 + 2x = -1 all on one side of the equation.

x^2 + 2x = -1

x^2 + 2x + 1 = -1 + 1

x^2 + 2x + 1 = 0

Now that the trinomial is on the left-hand side, let's factor the equation.

x^2 + 2x + 1 = 0

(x + 1)(x + 1) = 0

We can simplify this factored trinomial further to be:

(x + 1)(x + 1) = 0

(x + 1)^2 = 0

Cheers.

two time the quantity of seven less than one fourth is equal to four more than one third of the number. what is the number
kari74 [83]

Answer:

2(7) - 1/4 = 4 + 1/3x

x = 117/4

Step-by-step explanation:

solving an equation with one missing variable

step 1: multiply 2 * 7

ex: 14 - 1/4 = 4 + 1/3x

step 2: subtract 14 from 1/4

ex: 55/4 = 4 + 1/3x

step 3: subtract 4 from both sides of the equation

55/4 - 4 = 4 + 1/3x - 4   (39/4 = 1/3x)

step 4: divide both sides of the equation by 1/3

ex: 39/4 / 1/3 = 1/3x / 1/3   (x = 117/4 or x = 29 1/4)

step 5: to check your answer add the answer you got from the last equation which was 117/4 or 29 1/4 and input it into the original equation and get your final answer

ex: 2(7) - 1/4 = 4 + 1/3(117/4)

14 - 1/4 = 4 + 39/4

55/4 = 55/4 (if both sides of the equation are the same numbers like 55/4 = 55/4 then your answer is true)

What shape is the cross section formed by the intersection of a cone and a plane parallel to the base of the cone?
Ksju [112]
<h2>Answer:</h2>

A circle

<h2>Step-by-step explanation:</h2>

The representation of this problem is shown below. The cross-section is the name for a slice that cuts through a solid. If we move around the height of the cone through its volume, we will find that at every point the cross section will be a circle. The radius of that circle will depend on the point we are on. On the base of the cone, the circle will have the same radius of the cone and the radius will be decreasing when moving until we get to the apex.

For a tile pattern with the rule y = 6x + 4 (where x represents the figure number and y
Vinil7 [7]

Answer:

figure 6

Step-by-step explanation:

First you plug in the 40 into y which gives you 40=6x+4. Then, you subtract 4 on both sides and you're left with 36=6x so you divide 6 and x=6
