Question

The first step in factoring a trinomial of the form is to find two numbers, m and n, such that m + n = b and _____.

Answer 1

Correct choice is C). mn=ac

Explanation:

Given statement is that the first step in factoring a trinomial of the form is to find two numbers, m and n, such that m + n = b and _____.

We know that when we factor polynomial of type
`ax^2+bx+c` ,product of both numbers m and n must be same as product of a and c.

Hence correct choice is C). mn=ac
