multiply.\n$(x + 4)^{2}$\n$(x + 4)^{2}=\\square$ (simplify your answer.)

Explanation:

Step1: Expand using formula

Use the formula ((a + b)^2=a^{2}+2ab + b^{2}), where (a = x) and (b = 4). ((x + 4)^2=x^{2}+2\times x\times4+4^{2})

Step2: Simplify each term

Calculate (2\times x\times4 = 8x) and (4^{2}=16). (x^{2}+8x + 16)

Answer:

(x^{2}+8x + 16)
