Question

What is the sum of the two missing terms in this equation?

(m + 3)(m – 1) = m2 + ____ + ____ – 3


A) m


B) 3m


C) 4m


D) 2m

Answer 1

its D.2m im pretty sure sorry if i get you wrong 

Answer 2

D) 2m

Step-by-step explanation:

In order to identify the missing terms we need to expand the left side of the equation. So, let's use distributive propierty:

`(a+b)(c+d)=ac+ad+bc+bd`

Therefore:

`(m+3)(m-1)=m^2-m+3m-3=m^2+2m-3`

Hence, the sum of the two missing terms (-m and 3m) in the equation is: 2m
