expand (x^2-6x-3)(2x^2+2x-1)

expand

(x^{2} - 6 x - 3) (2 x^{2} + 2 x - 1)

2 x^{4} - 10 x^{3} - 19 x^{2} + 3

Solution steps

(x^{2} - 6 x - 3) (2 x^{2} + 2 x - 1)

Distribute parentheses

= x^{2} \cdot 2 x^{2} + x^{2} \cdot 2 x + x^{2} (- 1) - 6 x \cdot 2 x^{2} - 6 x \cdot 2 x - 6 x (- 1) - 3 \cdot 2 x^{2} - 3 \cdot 2 x - 3 (- 1)

Simplify

x^{2} \cdot 2 x^{2} + x^{2} \cdot 2 x + x^{2} (- 1) - 6 x \cdot 2 x^{2} - 6 x \cdot 2 x - 6 x (- 1) - 3 \cdot 2 x^{2} - 3 \cdot 2 x - 3 (- 1) : 2 x^{4} - 10 x^{3} - 19 x^{2} + 3

= 2 x^{4} - 10 x^{3} - 19 x^{2} + 3

lo g_{10} (10) (2)

(3 x - 2) (2 x + 1) (2 x + 1)

(- 2) - 3

\frac{42}{100}
