expand (5x^2+5x+7)(8x+6)

expand

(5 x^{2} + 5 x + 7) (8 x + 6)

40 x^{3} + 70 x^{2} + 86 x + 42

Solution steps

(5 x^{2} + 5 x + 7) (8 x + 6)

Distribute parentheses

= 5 x^{2} \cdot 8 x + 5 x^{2} \cdot 6 + 5 x \cdot 8 x + 5 x \cdot 6 + 7 \cdot 8 x + 7 \cdot 6

Simplify

5 x^{2} \cdot 8 x + 5 x^{2} \cdot 6 + 5 x \cdot 8 x + 5 x \cdot 6 + 7 \cdot 8 x + 7 \cdot 6 : 40 x^{3} + 70 x^{2} + 86 x + 42

= 40 x^{3} + 70 x^{2} + 86 x + 42

27 + 12 - 75

(k + 4)^{2}

\frac{26}{4 + 3}

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

(sec^{2} (x) - 1)^{2}
