Question

x2 + 8x + 12 = 0

Answer 1

x = -2; x = -6
x = -2; x = 6
x = 2; x = 6
x = 2; x = -6

Answer 2

whichh one?

Answer 3

x=-6,-2

Answer 4

so your first one

Answer 5

thanks!

Answer 6

(x + 7) (x - 15) = 0

Answer 7

The quadratic factors as (x+6)(x+2)=0 so the solutions are x=-6 or x=-2.

Answer 8

x = -7; x = 15
x = -7
x = 15
x = 7; x = -15

Answer 9

which one

Answer 10

You need an equation first

Answer 11

(x + 7) (x - 15) = 0

Answer 12

same thing as above:
x=-7 and x=15

Answer 13

x=-7 or x=15...they're both solutions.

Answer 14

x2 + 5x = 6



x = 1; x = -6
x = -1; x = -6
x = -1; x = 6
x = 1; x = 6

Answer 15

x=-6,1
x=-6,x=-1

Answer 16

A,B,C,D?

Answer 17

Smitty - when you factor as ( )( ) = 0, it means either the first factor is zero, the second is zero or they're both zero. The equation's true then for those x-values that make a factor equal to zero.

x2 + 5x - 6 =0 -> (x+6)(x-1)=0 so the answer is x = -6 or x = 1.

Answer 18

x = -1; x = -6 B!

Answer 19

x(x - 8) = 9



x = -1; x = 9
x = -1; x = -9
x = 1
x = 1; x = -9

Answer 20

x=-1,9 A

Answer 21

Smitty, you have to expand the left-hand side, subtract 9 from both sides and either factorize or complete the square or use the quadratic equation to figure out x.

Answer 22

x2 - 4 = 0



x = 2; x = -2
x = -2
no solutions
x = 2

Answer 23

x = +2 or -2

Answer 24

x=2

Answer 25

(x + 6) (5x - 3)



5x2 - 27x - 18
5x2 + 30x - 18
5x2 + 27x - 18
5x2 + 27x + 18

Answer 26

sorry accidently hit enter early x = 2, -2

Answer 27

i got it wrong haha ohwell

Answer 28

5x^2+27x-18

Answer 29

x2 - 10x + 21 = 0



x = 3; x = -7
x = 3; x = 7
x = -3; x = 7
x = -3; x = -7

Answer 30

x=3,7 B

Answer 31

x2 - 4 = 0



x = 2; x = -2
x = 2
no solutions
x = -2


9. Multiply the binomials:
(3x + 4) (5x - 4)



15x2 + 8x - 16
15x2 + 8x + 16
15x2 + 20x - 16
15x2 - 8x - 16


10. Find the solution(s) for x:
x2 + 7x + 10 = 0



x = -2; x = 5
x = 2; x = 5
x = 2; x = -5
x = -2; x = -5
