Question

Simplify: (5a + 3b) – (5a - 3b)3

Answer 1

Answer:

$\huge \tt \red{Question:-}$

$\bf(5a + 3b) - (5a - 3b) ^{2}$

$\huge \tt \green{Answer:-}$

$\red \rightarrow \tt \: 5a+3b-(5a-3b) ^{2}$

$\bf \red \rightarrow \tt\color{k}5a + 3b - [(5a) ^{2} + 2 \times 5a( - 3b) + ( - 3b) ^{2} ]$

$\bf \red \rightarrow \tt 5a + 3b - ( {5}^{2} \times {a}^{2} - 2 \times 5a \times 3b + (3b) ^{2} ]$

$\bf \red \rightarrow \tt 5a + 3b - (25 {a}^{2} - 2 \times 5 \times 3ab + {3}^{2} \times {b}^{2} ]$

$\bf \red \rightarrow \tt5a + 3b - (25 {a}^{2} - 30ab + 9 {b}^{2} )$

$\bf \red \rightarrow \tt 5a + 3b - 25 {a}^{2} + 30ab - 9 {b}^{2}.$

Answer 2

Answer:

$\beta simplify$

Step-by-step explanation:

$(5a + 3b) - (5a - 3b) }^{2}$p
