Question

100 POINTS! I REALLY NEED TO GET THIS CORRECT! Factor the quadratic trinomial.

x^2−3x−18
Hint: To use type an exponent, use the caret symbol (^) by using the keys shift + 6

Answer 1

By inspection you need 2 numbers that multiply together to -18 and sum to -3. These numbers are -6 and 3. Therefore we have:

x2−3x−18=(x−6)(x+3)
