Answer:

2a-3 and a+4

Step-by-step explanation:

Given the equation

2a²+8a -15 = 3a - 3

We are to find one of its factors

Equate the expression to zero

2a²+8a -15 = 3a - 3

2a²+8a -15 - 3a + 3 = 0

Collect the like terms

2a²+8a - 3a - 15 + 3= 0

2a²+5a - 12= 0

Factorize

2a²+8a-3a - 12= 0

2a(a+4)-3(a+4) = 0

(2a-3)(a+4) = 0

Hence the factors are 2a-3 and a+4

The answer would be 
x² + 18x + 81 = 44 + 81

To complete the square, we look at the value of b (the coefficient of x).  We take half of it, then square it; this is the number that gets added to both sides.

18/2 = 9; 9²=81

Therefore we add 81 to both sides.
