expand 3(8+Δx)^2

Solution

expand

3 (8 + Δ x)^{2}

Solution

192 + 48Δ x + 3 Δ^{2} x^{2}

Solution steps

3 (8 + Δ x)^{2}

(8 + Δ x)^{2} = 64 + 16Δ x + Δ^{2} x^{2}

= 3 (Δ^{2} x^{2} + 16Δ x + 64)

Distribute parentheses

= 3 \cdot 64 + 3 \cdot 16Δ x + 3 Δ^{2} x^{2}

Simplify

3 \cdot 64 + 3 \cdot 16Δ x + 3 Δ^{2} x^{2} : 192 + 48Δ x + 3 Δ^{2} x^{2}

= 192 + 48Δ x + 3 Δ^{2} x^{2}
