Step 1 : Analysis

Given :

$(x+4)}^{2$

Step 2 : Solution

Using the formula$(a+b)}^{2}={a}^{2}+2ab+{b}^{2$

$(x+4)}^{2}={x}^{2}+2\times x\times 4+{4}^{2$

${(x+4)}^{2}={x}^{2}+8x+16$

Therefore

${(x+4)}^{2}={x}^{2}+8x+16$

Given :

Step 2 : Solution

Using the formula

Given:

$(x+4)}^{2$

=(x+4)(x+4)

=(x)(x)+(x)(4)+(4)(x)+(4)(4)

$={x}^{2}+4x+4x+16$

$={x}^{2}+8x+16$

Result:

${x}^{2}+8x+16$

=(x+4)(x+4)

=(x)(x)+(x)(4)+(4)(x)+(4)(4)

Result:
