expand (7x^4+6)^2

Solution

expand

(7 x^{4} + 6)^{2}

Solution

49 x^{8} + 84 x^{4} + 36

Solution steps

(7 x^{4} + 6)^{2}

Apply Perfect Square Formula:

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

(7 x^{4} + 6)^{2} = (7 x^{4})^{2} + 2 \cdot 7 x^{4} \cdot 6 + 6^{2}

= (7 x^{4})^{2} + 2 \cdot 7 x^{4} \cdot 6 + 6^{2}

Simplify

(7 x^{4})^{2} + 2 \cdot 7 x^{4} \cdot 6 + 6^{2} : 49 x^{8} + 84 x^{4} + 36

= 49 x^{8} + 84 x^{4} + 36
