X^2 + 6x +9
(x+3) (x+3)
x+3 = 0
x = -3
answer: x=-3
Answer: -20, 48
Step-by-step explanation: 5 x -4 = -20 6 x 8 = 48
to solve this we need to isolate the x variable.
subtract 1 from each side: [3x+4] = 6
now we can drop the parentheses and subtract 4 from each side: 3x = 2
divide each side by 3: x = 2/3
