(469 + 174)^2 - (469 - 174)^2 (469 × 174) = ?

Answer: Option B

$$\begin{array}{rl}& \frac{{\left(469+174\right)}^2-{\left(469-174\right)}^2}{\left(469\times 174\right)}=?\\ & \text{We}\text{ know that},\\ & 4ab={\left(a+b\right)}^2-{\left(a-b\right)}^2\\ & \therefore \frac{{\left(469+174\right)}^2-{\left(469-174\right)}^2}{\left(469\times 174\right)}\\ & =\frac{4\times 469\times 174}{469\times 174}\\ & =4\end{array}$$
