expand 2(x^2+x-10)^2

expand

2 (x^{2} + x - 10)^{2}

2 x^{4} + 4 x^{3} - 38 x^{2} - 40 x + 200

Solution steps

2 (x^{2} + x - 10)^{2}

(x^{2} + x - 10)^{2} = x^{4} + 2 x^{3} - 19 x^{2} - 20 x + 100

= 2 (x^{4} + 2 x^{3} - 19 x^{2} - 20 x + 100)

Distribute parentheses

= 2 x^{4} + 2 \cdot 2 x^{3} + 2 (- 19 x^{2}) + 2 (- 20 x) + 2 \cdot 100

Apply minus-plus rules

+ (- a) = - a

= 2 x^{4} + 2 \cdot 2 x^{3} - 2 \cdot 19 x^{2} - 2 \cdot 20 x + 2 \cdot 100

Simplify

2 x^{4} + 2 \cdot 2 x^{3} - 2 \cdot 19 x^{2} - 2 \cdot 20 x + 2 \cdot 100 : 2 x^{4} + 4 x^{3} - 38 x^{2} - 40 x + 200

= 2 x^{4} + 4 x^{3} - 38 x^{2} - 40 x + 200

(4 x - 3 y = 1, 4) (- 2 x + 5 y = - 14)

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

f (- 3, - 2) x^{2} + x y^{3}

(3 + e^{6 t})^{2}

x + (x + 2)
