What are the solutions to x2 + 8x + 7 = 0?

x = -7/10

Another way of writing -7/10 is -0.7. Both ways are correct.

Step-by-step explanation:

x * 2 + 8x + 7 = 0

1. Add similar elements: 2x + 8x = 10x

10x + 7 = 0

2. Subtract 7 from both sides.

10x + 7 - 7 = 0 - 7

3. Simplify.

10x = -7

4. Divide both sides by 10.

10x / 10 = -7 / 10

5. Simplify.

x = -7/10

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
