expand-3(-2x)^2+5(-2x)

expand

- 3 (- 2 x)^{2} + 5 (- 2 x)

- 12 x^{2} - 10 x

Solution steps

- 3 (- 2 x)^{2} + 5 (- 2 x)

Remove parentheses:

(- a) = - a

= - 3 (- 2 x)^{2} - 5 \cdot 2 x

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

= - 2^{2} \cdot 3 x^{2} - 5 \cdot 2 x

Multiply the numbers:

5 \cdot 2 = 10

= - 2^{2} \cdot 3 x^{2} - 10 x

3 \cdot 2^{2} x^{2} = 12 x^{2}

= - 12 x^{2} - 10 x

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

\frac{14}{3 ( 2 s + 3 )}

\frac{( - 3 - x ) ^{2}}{2}

\frac{a s + b + 3 a + 1}{s ( s + 1 ) ( s + 2 )}

2 a - (x - c)^{2} + y^{2}
