Solve the equation. x^2 − 6x − 7 = 0
a) x = 7
b) x = 1
c) x = 1 or x = −7
d) x = −1 or x = 7

Here is your answer

D) x= -1 or x= 7

REASON:

Given equation-

Split the middle term

Taking common from the terms

Now,

x+1=0 or x-7=0

x= -1 or x= 7

the answer is 1/4

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
