expand (x^2+15)^2

Solution

expand

(x^{2} + 15)^{2}

Solution

x^{4} + 30 x^{2} + 225

Solution steps

(x^{2} + 15)^{2}

Apply Perfect Square Formula:

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

(x^{2} + 15)^{2} = (x^{2})^{2} + 2 x^{2} \cdot 15 + 1 5^{2}

= (x^{2})^{2} + 2 x^{2} \cdot 15 + 1 5^{2}

Simplify

(x^{2})^{2} + 2 x^{2} \cdot 15 + 1 5^{2} : x^{4} + 30 x^{2} + 225

= x^{4} + 30 x^{2} + 225
