expand 8(x+Δx)^2

expand

8 (x + Δ x)^{2}

8 x^{2} + 16Δ x^{2} + 8 Δ^{2} x^{2}

Solution steps

8 (x + Δ x)^{2}

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

= 8 (x^{2} + 2Δ x^{2} + Δ^{2} x^{2})

Distribute parentheses

= 8 x^{2} + 8 \cdot 2Δ x^{2} + 8 Δ^{2} x^{2}

Multiply the numbers:

8 \cdot 2 = 16

= 8 x^{2} + 16Δ x^{2} + 8 Δ^{2} x^{2}

\frac{1}{( s ^{2} + 4 s + 13 ) ^{2}}

\frac{1}{k ( k - 1 )}

(2 x - y = 1) \cdot 2

A (- 6, 12) B (6, - 2)
