Answer:
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
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
