Answer:

x = 7 and x = -1

Step-by-step explanation:

<u>Step 1: Factor</u>

x^2 - 6x - 7 = 0

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

<u>Step 2: Solve for x</u>

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

x - 7 = 0 and x + 1 = 0

x - 7 + 7 = 0 + 7 and x + 1 - 1 = 0 - 1

x = 7 and x = -1

Answer: x = 7 and x = -1

Find the value of "m" that gives infinitely many solutions ! PLEASE HELP!!

Answer: 2x

Step-by-step explanation: 18+2(x-7)=4+M. First distribute 2 to (x-7), then you will be left with 18+2x-14=4+M. You can further simplify the left side of the equation by subtracting 14 from 18, now you are left with 2x+4=4+M. Subtract 4 from both sides to solve for M, 2x=M.
