What are the solutions to x2 - 6x - 7 = 0?

Answer: x is - 1 & 7

Step-by-step explanation:

X2-6x-7=0

Quadratic equation

Variables of - 7 that will give-6 are

-7 & + 1

X2-7x+x-7=0

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

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

X+1=0

X = - 1 or

X-7=0

X = 7

Therefore,

X is either - 1 & 7

x=7 x=-1

Step-by-step explanation:

x^2 - 6x - 7 = 0

Factor

What two numbers multiply to - 7 and add to - 6

-7*1 = -7

-7+1 = - 6

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

Using the zero product property

x-7 = 0 x+1 = 0

x=7 x=-1
