Question

Find the value of
$(3x - 4y)^{2}$
​

Answer 1

Answer:

${(3x - 4y)}^{2}$

${(3x)}^{2} - 2(3x)(4y) + {(4y)}^{2}$

${9x}^{2} - 24xy + {16y}^{2}$

$ans. \: \: {9x}^{2} - 24xy + {16y}^{2}$

Hope it helps.

Answer 2

Answer:

9x² - 24xy + 16y²

Step-by-step explanation:

(3x - 4y)²

= (3x)² - ( 2 x 3x x 4y ) + (4y)²

= (3² × x²) - 24xy + (4² × y²)

= 9x² - 24xy + 16y²
