expand 2(x+Δx)^2

expand

2 (x + Δ x)^{2}

2 x^{2} + 4Δ x^{2} + 2 Δ^{2} x^{2}

Solution steps

2 (x + Δ x)^{2}

(x + Δ x)^{2} = x^{2} + 2Δ x^{2} + Δ^{2} x^{2}

= 2 (x^{2} + 2Δ x^{2} + Δ^{2} x^{2})

Distribute parentheses

= 2 x^{2} + 2 \cdot 2Δ x^{2} + 2 Δ^{2} x^{2}

Multiply the numbers:

2 \cdot 2 = 4

= 2 x^{2} + 4Δ x^{2} + 2 Δ^{2} x^{2}

(- 2 + \frac{3 i}{n})^{2}

\frac{( x - 1 ) ^{2} ln ( x )}{( x - 1 ) ^{2} + y ^{2}}

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

(sec (x) - csc (x)) (cos (x) + sin (x))

(2 + 2 cos (x))^{2}
