Factorization of the expression y^2 + y-6 is?
- (y+2)(y-3)
- (y+3)(y-2)
- (y+3)(x-4)
- None
Explanation
To factorize the expression y^2 + y - 6, we need to find two numbers whose product is -6 and whose sum is 1 (the coefficient of the middle term).
These numbers are 3 and -2, so we can write:
y^2 + y - 6 = (y + 3)(y - 2)
