x^2 + 6x = - 9

x^2 + 6x + 9 = 0

(x + 3)(x + 3) = 0

x = -3

x^2 + 6x + 9 = 0

(x + 3)(x + 3) = 0

x = -3

(x - 8)^2 = 48

x - 8 = ± sqrt 48

x - 8 = ± 4 sqrt 3

x = 8 ± 4 sqrt 3

x - 8 = ± sqrt 48

x - 8 = ± 4 sqrt 3

x = 8 ± 4 sqrt 3

3x^2 = 147

x^2 = 147/3

x^2 = 49

x = 7 or -7.

x^2 = 147/3

x^2 = 49

x = 7 or -7.

x^2 - 49 = 0

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

x = -7 or x = 7

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

x = -7 or x = 7

y^2 + 7y = 18

y^2 + 7y - 18 = 0

(y - 2)(y + 9) = 0

y - 2 = 0 or y + 9 = 0

y = 2 or y = -9

the equation that could be used to solve y^2+7y=18 by factoring is y - 2 = 0 and y + 9 = 0

y^2 + 7y - 18 = 0

(y - 2)(y + 9) = 0

y - 2 = 0 or y + 9 = 0

y = 2 or y = -9

the equation that could be used to solve y^2+7y=18 by factoring is y - 2 = 0 and y + 9 = 0
