Multiply two binomials

Full solution

Q. Expand.

\newline

Your answer should be a polynomial in standard form.

\newline

(x-4)(x+7)=

Performing Multiplication: Now, we will perform the multiplication for each term. $\newline$ $x(x) = x^2$ $\newline$ $x(7) = 7x$ $\newline$ $-4(x) = -4x$ $\newline$ $-4(7) = -28$ $\newline$ So, the expression becomes: $\newline$ $x^2 + 7x - 4x - 28$
Combining Like Terms: Next, we combine like terms, which are the terms with $x$ . $7x - 4x = 3x$ So, the expression now simplifies to: $x^2 + 3x - 28$
