Astudent is deriving the quadratic formula. her first two steps are shown. step 1: –c = ax2 + bx step 2: -c = a[x^2+b/ax] which best explains or justifies step 2? division property of equality factoring the binomial completing the square subtraction property of equality

Given choices:

(1) division property of equality

(2) factoring the binomial

(3)completing the square

(4)subtraction property of equality

Answer : (2) factoring the binomial

Step 1:

Step 2:

In step 2, 'a' is taken out from . when we take out 'a' we divide each term by 'a'. so it becomes

'a' is factored out in step 2. we call it as factoring a binomial.

because its not ur topic and its not for is for homework not that.
