Question

For the trinomial ​3x^2 + 22x + 7, choose two numbers whose product is 21 and whose sum is 22

Answer 1

Answer:

When a trinomial is in the form of ax2 + bx + c, where a is a coefficient other than 1, look first for common factors for all three terms. Factor out the common factor first, then factor the remaining simpler trinomial. If the remaining trinomial is still of the form ax2 + bx + c, find two integers, r and s, whose sum is b and whose product is ac.
