Step-by-step explanation:
Change it into this 
(2x-3)(2x-3) 
Then multiply the insides and outsides and add them 
(2x*2x) + (2x* -3) + (-3*2x) + (-3*-3) 
Simplify
4x^2 - 6x -6x + 9 
Simplify again 
4x^2 - 12x + 9

Answer:
n = -5, 3.
Step-by-step explanation:
n^2 + 2n - 15 = 0
Let's check if we can factor this quadratic:
We need 2 numbers whose product is -15 and whose sum is +2.
There are 2 such numbers and they are +5 and -3, so the factors are:
(n + 5)(n - 3) = 0.
n + 5 = 0 or n - 3 = 0 
therefore the zeroes are -5 and 3.
