expand (5x^2-1)(-7x^2+x+3)

expand

(5 x^{2} - 1) (- 7 x^{2} + x + 3)

- 35 x^{4} + 5 x^{3} + 22 x^{2} - x - 3

Solution steps

(5 x^{2} - 1) (- 7 x^{2} + x + 3)

Distribute parentheses

= 5 x^{2} (- 7 x^{2}) + 5 x^{2} x + 5 x^{2} \cdot 3 - 1 \cdot (- 7 x^{2}) - 1 \cdot x - 1 \cdot 3

Simplify

5 x^{2} (- 7 x^{2}) + 5 x^{2} x + 5 x^{2} \cdot 3 - 1 \cdot (- 7 x^{2}) - 1 \cdot x - 1 \cdot 3 : - 35 x^{4} + 5 x^{3} + 22 x^{2} - x - 3

= - 35 x^{4} + 5 x^{3} + 22 x^{2} - x - 3

(- \frac{3}{2})^{7} \cdot (- \frac{2}{3})^{4}

\frac{39}{13}

(x + 1)^{2} (x + 2)

2 (\frac{x + 7}{2}) - 7

\frac{\frac{a ^{6}}{5}}{3 a ^{3}}
