expand (-4x)(8x)-1-x^2-4x

expand

(- 4 x) (8 x) - 1 - x^{2} - 4 x

- 33 x^{2} - 4 x - 1

Solution steps

(- 4 x) (8 x) - 1 - x^{2} - 4 x

Remove parentheses:

(a) = a

= - 4 x \cdot 8 x - 1 - x^{2} - 4 x

4 x \cdot 8 x = 32 x^{2}

= - 32 x^{2} - 1 - x^{2} - 4 x

Group like terms

= - 32 x^{2} - x^{2} - 4 x - 1

Add similar elements:

- 32 x^{2} - x^{2} = - 33 x^{2}

= - 33 x^{2} - 4 x - 1

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

(y - x y) d x + x d y

2 - \frac{1}{4}

\frac{x + a}{( a + ab ) ( - ba + a )}

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