expand 8(4x^2+9x+1)^2

expand

8 (4 x^{2} + 9 x + 1)^{2}

128 x^{4} + 576 x^{3} + 712 x^{2} + 144 x + 8

Solution steps

8 (4 x^{2} + 9 x + 1)^{2}

(4 x^{2} + 9 x + 1)^{2} = 16 x^{4} + 72 x^{3} + 89 x^{2} + 18 x + 1

= 8 (16 x^{4} + 72 x^{3} + 89 x^{2} + 18 x + 1)

Distribute parentheses

= 8 \cdot 16 x^{4} + 8 \cdot 72 x^{3} + 8 \cdot 89 x^{2} + 8 \cdot 18 x + 8 \cdot 1

Simplify

8 \cdot 16 x^{4} + 8 \cdot 72 x^{3} + 8 \cdot 89 x^{2} + 8 \cdot 18 x + 8 \cdot 1 : 128 x^{4} + 576 x^{3} + 712 x^{2} + 144 x + 8

= 128 x^{4} + 576 x^{3} + 712 x^{2} + 144 x + 8

\frac{- 4 x - 20}{3 ( y ^{2} - 3 - 2 y )}
