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

Correct choice is C). mn=ac

Step-by-step 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 ,product of both numbers m and n must be same as product of a and c.

Hence correct choice is C). mn=ac

d is correct

step-by-step explanation:

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
