expand (3p-2q+5)(3p-2q-5)

expand

(3 p - 2 q + 5) (3 p - 2 q - 5)

9 p^{2} - 12 pq + 4 q^{2} - 25

Solution steps

(3 p - 2 q + 5) (3 p - 2 q - 5)

Distribute parentheses

= 3 p \cdot 3 p + 3 p (- 2 q) + 3 p (- 5) - 2 q \cdot 3 p - 2 q (- 2 q) - 2 q (- 5) + 5 \cdot 3 p + 5 (- 2 q) + 5 (- 5)

Simplify

3 p \cdot 3 p + 3 p (- 2 q) + 3 p (- 5) - 2 q \cdot 3 p - 2 q (- 2 q) - 2 q (- 5) + 5 \cdot 3 p + 5 (- 2 q) + 5 (- 5) : 9 p^{2} - 12 pq + 4 q^{2} - 25

= 9 p^{2} - 12 pq + 4 q^{2} - 25

x^{4} - 6 x^{3} - 8 x^{2} + 96 x - 128

m^{6} n - m^{2} n^{5}

\frac{2}{3 + 5}

24 x^{3} y^{4} - 18 x^{2} y^{5}

x^{2} + 12 x + 36 - 9 y^{2}
