expand (100-2pix)^2

expand

(100 - 2 π x)^{2}

4 π^{2} x^{2} - 400 π x + 10000

Solution steps

(100 - 2 π x)^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

a = 100, b = 2 π x

= 10 0^{2} - 2 \cdot 100 \cdot 2 π x + (2 π x)^{2}

Simplify

10 0^{2} - 2 \cdot 100 \cdot 2 π x + (2 π x)^{2} : 10000 - 400 π x + 4 π^{2} x^{2}

= 10000 - 400 π x + 4 π^{2} x^{2}

Rewrite in standard form

= 4 π^{2} x^{2} - 400 π x + 10000

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

((s + t)^{2})^{3}

(x - 2) (x + 5, 0.5)

(2 x + 1) \cdot e^{5}

\frac{( x + 2 ) ( x - 1 )}{( x - 5 ) ( x + 4 )}
