Solution

expand

(x + 20)^{2}

Solution

x^{2} + 40 x + 400

Solution steps

(x + 20)^{2}

Apply Perfect Square Formula:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

(x + 20)^{2} = x^{2} + 2 x \cdot 20 + 2 0^{2}

= x^{2} + 2 x \cdot 20 + 2 0^{2}

Simplify

x^{2} + 2 x \cdot 20 + 2 0^{2} : x^{2} + 40 x + 400

= x^{2} + 40 x + 400
