Question

Find the solution set.
x2 + 6x - 7=0
Separate the two values with a comma.

Answer 1

Hey there! :)

Answer:

x = -7, 1

Step-by-step explanation:

0 = x² + 6x - 7

Factor the polynomial, giving us:

(x + 7)(x - 1) = 0

Set each factor equal to 0:

x + 7 = 0

x = -7

----------

x - 1 = 0

x = 1

Therefore, the solution set is:

x = -7, 1

Answer 2

Answer:

Step-by-step explanation:

x²+6x-7=0

x²+7x-x-7=0

x(x+7)-1(x+7)=0

(x+7)(x-1)=0

x=-7,1
