expand 2(x^2-7x+7)^2

expand

2 (x^{2} - 7 x + 7)^{2}

2 x^{4} - 28 x^{3} + 126 x^{2} - 196 x + 98

Solution steps

2 (x^{2} - 7 x + 7)^{2}

(x^{2} - 7 x + 7)^{2} = x^{4} - 14 x^{3} + 63 x^{2} - 98 x + 49

= 2 (x^{4} - 14 x^{3} + 63 x^{2} - 98 x + 49)

Distribute parentheses

= 2 x^{4} + 2 (- 14 x^{3}) + 2 \cdot 63 x^{2} + 2 (- 98 x) + 2 \cdot 49

Apply minus-plus rules

+ (- a) = - a

= 2 x^{4} - 2 \cdot 14 x^{3} + 2 \cdot 63 x^{2} - 2 \cdot 98 x + 2 \cdot 49

Simplify

2 x^{4} - 2 \cdot 14 x^{3} + 2 \cdot 63 x^{2} - 2 \cdot 98 x + 2 \cdot 49 : 2 x^{4} - 28 x^{3} + 126 x^{2} - 196 x + 98

= 2 x^{4} - 28 x^{3} + 126 x^{2} - 196 x + 98

\frac{2 x - 3}{5}

- 1.5 (5 x + 2 y = - 9)

(4 a^{2} + 3 a + 6)^{7}

\frac{3 y ^{2} - 1 - 2 y}{2 ( - 1 + x )}

(r - 3 - 13)^{2}
