Chapter 7: Q20. (page 463)

Find each product.
${(x + 3)}^{2}$

Short Answer

Expert verified

The required product is represented by $x^{2} + 9 + 6 x$ .

Step by step solution

Step 1. Determine the identity of polynomial that can be used.

The provided polynomial indicates the left side of the identity ${(a + b)}^{2} = a^{2} + b^{2} + 2 a b$ so this identity can be used.

Step 2. Take the help of obtained identity.

Substitute x in place of a and 3 in place of b into the right side of the obtained identity.

$x^{2} + {(3)}^{2} + 2 (3 x)$

Step 3. Perform the simplification.

Write the exponential and multiplicative terms in simplest form.

$x^{2} + 9 + 6 x$
