Question

(a + b) (c +d + e) = ac + ad + ae + _ + _ + _

Answer 1

Given:

`(a+b)(c+d+e)`

We multiply each term of the first factor by each term of the other factor:

`\begin{gathered} =a\cdot c+a\cdot d+a\cdot e+b\cdot c+b\cdot d+b\cdot e \\ =ac+ad+ae+bc+bd+be \end{gathered}`

Answer: ac + ad + ae + bc + bd + be
