Question

Multiply these binomials.

(4x + 3)(x + 1) =

How do I solve this?

Can someone put it into simple steps (very simple steps)?

Please and thank you!

Answer 1

\[\Large (a+b)(c+d)\]
When you multiply two binomials, you use the distributive property twice
\[\Large (a+b)(c+d)=a(c+d)+b(c+d)=ac+ad+bc+bd\]

Answer 2

So, for example, if you were to multiply (2x+3) by (x+7) you would get
\[(2x+3)(x+7)=2x(x+7)+3(x+7)=2x^2+14x+3x+21=2x^2+15x+21\]

Answer 3

17x

Answer 4

Thank you. :)

Answer 5

that is not the answer but an error in $$2x^2+15x+21$$it should be $$2x^2+17x+21$$
