expand 3(4x+5)^3

Solution

expand

3 (4 x + 5)^{3}

Solution

192 x^{3} + 720 x^{2} + 900 x + 375

Solution steps

3 (4 x + 5)^{3}

Expand

(4 x + 5)^{3} : 64 x^{3} + 240 x^{2} + 300 x + 125

= 3 (64 x^{3} + 240 x^{2} + 300 x + 125)

Distribute parentheses

= 3 \cdot 64 x^{3} + 3 \cdot 240 x^{2} + 3 \cdot 300 x + 3 \cdot 125

Simplify

3 \cdot 64 x^{3} + 3 \cdot 240 x^{2} + 3 \cdot 300 x + 3 \cdot 125 : 192 x^{3} + 720 x^{2} + 900 x + 375

= 192 x^{3} + 720 x^{2} + 900 x + 375
