Question

Expand:- (3x upon 5 - 10y upon 3)^2

​

Answer 1

Step-by-step explanation:

(3x/5-10y/3)²

(3x/5)²+(10y/3)²-2(3x/5)(10y/3)

9x²/25+100y²/9-60xy/15

9x²/25+100y²/9-4xy

HOPE IT HELPS YOU

Answer 2

(3x/5-10y/3)^2

Use the formula (a-b)^2 = a^2-2ab+b^2

${( \frac{3x}{5} - \frac{10y}{3} )}^{2}$

$({ \frac{9x}{15} - \frac{50y}{15}) }^{2}$

$( { \frac{9x - 50y}{15}) }^{2}$
