Question

ans. it pls.
guys

if the last and is not clear the read it from here.
last question.
Factorise 4a square - 9b square -2a -3b.
Ans.(2a +3b) (2a-3b -1)

don't answer second last question

Answer 1

Given Equation is 4a^2 - 9b^2 - 2a - 3b

= > (2a)^2 - (3b)^2 - 2a - 3b

We know that a^2 - b^2 = (a + b)(a - b)

= > (2a + 3b)(2a - 3b) - (2a + 3b)

= > (2a + 3b)[(2a - 3b) - 1)]

= > (2a + 3b)(2a - 3b - 1).



Hope this helps!

Answer 2

HEY HERE IS YOUR ANSWER ☺☺☺

${4a}^{2} - {9b}^{2} - 2a - 3b \\ \\ ( {4a}^{2} - {9b}^{2} ) - 2a - 3b \\ \\ using \: \: identity \: \: {a}^{2} - {b}^{2} = (a + b)( a- b) \\ \\ ({(2a)}^{2} - {(3b)}^{2} ) - 2a - 3b \\ \\ (2a + 3b)(2a - 3b) - 2a - 3b \\ \\ (2a + 3b)(2a - 3b) - 1(2a + 3b) \\ \\ (2a + 3b)(2a - 3b - 1)$

HOPE IT HELPS ☺☺☺☺
