Question

solve using appropriate property (3P– 5 )2

Answer 1

$\huge \mathbb \red{ANSWER \: : }$

(a-b)² = a²+b²-2ab

$\sf \: {(3p - 5)}^{2} = {(3p)}^{2} + {(5)}^{2} - 2(3p)(5) \\ \\ \sf \: {(3p - 5)}^{2} = {9p}^{2} + 25 - 30p$

Answer 2

Answer:

9p²+25-30p

Step-by-step explanation:

By (a-b)²=(a²+b²-2ab)

(3p-5)²

={(3p)²+(5)²-(2×3p×5)}

=9p²+25-30p
