Solve (X+4)(3+X) Given X=4: Binomial Multiplication Problem

Question

Solve the exercise below given that: $X=4$

$(X+4)(3+X)$

00:09 Let's tackle this math problem together!

00:13 First, we'll substitute X with 4, based on the given data. Let's solve it step by step.

00:27 Next, calculate each part inside the parentheses separately.

00:32 Remember, there's multiplication between these parentheses.

00:36 And there you have it, that's our solution! Great job!

We start by substituting the value of $X$

$(4+4)(3+4)$

First, we perform the calculation in parentheses

$(8)(7)$

After this, we solve the parentheses and can continue with the simple multiplication exercise.

$7\times 8=56$
