Question

find the value of: (9a+6b)(6a+9b)​

Answer 1

Answer:

use the algebric algorithm to solve it

Answer 2

$\huge{\pink{\sf{Answer}}}$

$\implies \large{ \green{ \sf{Find \: the \: value \: of \: (9a + 6b)(6a + 9b).}}}$

$\implies \large{ \red{ \sf{Solution}}}$

• Firstly of all we have to multiply 9a by 6a+9b and then after we have to multiply 6b by 6a+9b.

$\implies \large{ \purple{ \sf{9a \times (6a + 9b) + 6b \times(6a + 9b)}}}$

$\implies \large{ \purple{ \sf{(54 {a}^{2} + 81ab) + (36ab +54 {b}^{2} )}}}$

$\implies \large{ \purple{ \sf{Now \: pair \: the \: like \: terms \: togther.}}}$

$\implies \large{ \purple{ \sf{(81ab + 36ab) + 54 {a}^{2} + 54{b}^{2} }}}$

$\implies \large{ \purple{ \sf{117ab +54 {a}^{2} + 54 {b}^{2} }}}$

$\implies \large{ \red{ \sf{So \: its \: answer \: is \: 117ab + 54 {a}^{2} + 54 {b}^{2}. }}}$
