expand pi*(2x+1)^2

Solution

expand

π \cdot (2 x + 1)^{2}

Solution

4 π x^{2} + 4 π x + π

Solution steps

π (2 x + 1)^{2}

(2 x + 1)^{2} = 4 x^{2} + 4 x + 1

= π (4 x^{2} + 4 x + 1)

Distribute parentheses

= π 4 x^{2} + π 4 x + π 1

= 4 π x^{2} + 4 π x + 1 π

Multiply:

1 π = π

= 4 π x^{2} + 4 π x + π
