expand (-x^2+4)^2

Solution

expand

(- x^{2} + 4)^{2}

Solution

x^{4} - 8 x^{2} + 16

Solution steps

(- x^{2} + 4)^{2}

Apply Perfect Square Formula:

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

(- x^{2} + 4)^{2} = (- x^{2})^{2} + 2 (- x^{2}) \cdot 4 + 4^{2}

= (- x^{2})^{2} + 2 (- x^{2}) \cdot 4 + 4^{2}

Simplify

(- x^{2})^{2} + 2 (- x^{2}) \cdot 4 + 4^{2} : x^{4} - 8 x^{2} + 16

= x^{4} - 8 x^{2} + 16
