Question

100x^2 - 80xy + 16y^2

Answer 1

Answer:

(10x-4y)² = 100x²+16y²-80xy

Answer 2

$\huge \red {answer}$

$100 {x}^{2} - 80xy + 16y {}^{2} \\ \\ it \: looks \: like \: a {}^{2} + b {}^{2} - 2ab \: = {(a + b)}^{2} \\ \\ so \: 100 = {10}^{2} \: \: 16 = {4}^{2} also \: 2 \times 4 \times 10 = 80 \\ \\ so \: 100 {x}^{2} - 80xy + 16 {y}^{2} = {(10x + 4y)}^{2}$
