expand (49-x^2)^2

Solution

expand

(49 - x^{2})^{2}

Solution

2401 - 98 x^{2} + x^{4}

Solution steps

(49 - x^{2})^{2}

Apply Perfect Square Formula:

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

(49 - x^{2})^{2} = 4 9^{2} - 2 \cdot 49 x^{2} + (x^{2})^{2}

= 4 9^{2} - 2 \cdot 49 x^{2} + (x^{2})^{2}

Simplify

4 9^{2} - 2 \cdot 49 x^{2} + (x^{2})^{2} : 2401 - 98 x^{2} + x^{4}

= 2401 - 98 x^{2} + x^{4}
