expand (7x^2+5x+7)(4x-6)

expand

(7 x^{2} + 5 x + 7) (4 x - 6)

28 x^{3} - 22 x^{2} - 2 x - 42

Solution steps

(7 x^{2} + 5 x + 7) (4 x - 6)

Distribute parentheses

= 7 x^{2} \cdot 4 x + 7 x^{2} (- 6) + 5 x \cdot 4 x + 5 x (- 6) + 7 \cdot 4 x + 7 (- 6)

Simplify

7 x^{2} \cdot 4 x + 7 x^{2} (- 6) + 5 x \cdot 4 x + 5 x (- 6) + 7 \cdot 4 x + 7 (- 6) : 28 x^{3} - 22 x^{2} - 2 x - 42

= 28 x^{3} - 22 x^{2} - 2 x - 42

\frac{8 x ^{3} + 12 x ^{2}}{4 x}

(csc (θ) - 1) (csc (θ) + 1)

\frac{- 3}{3 2}

3 (- 5) (- 2)

\frac{4}{5} + \frac{2}{x}
