Answer 1

Do you know completing the square?

Answer 2

what

Answer 3

????

Answer 4

coefficient of x² multiplied by the constant
3 x -8=-24
you want two numbers to multiply to give -24 and add to give the coefficient of x which is 5

for this solution you get +8 and -3
replace 5x with +8x -3x
so you have
3x² -3x +8x -8

take out the common factor

3x(x-1) + 8(x-1)

(3x+8)(x-1)
