Answer:
We factories them by using splitting the middle term.
Step-by-step explanation:
18x^2 + 3x - 15 = 6x^2 + x - 5
= 6x^2 + 6x - 5x - 5
= 6x(x+1) - 5(x+1)
= (6x-5)(x+1)
On solving further, we get
x = 5/6 or x = -1
5x^2 + 32x + 12 = 5x^2 + 30x + 2x + 12
= 5x(x+6) + 2(x+6)
= (5x+2)(x+6)
On solving further, we get
x = -2/5 or x = -6
