Answer 1

Answer:

Step-by-step explanation:

sorry i cant

Answer 2

SolUtioN:-

$⇒ 2{x}^{2} + 9x - 5$

$⇒2 {x}^{2} + (10 - 1)x - 5$

$⇒2 {x}^{2} + 10x - x - 5$

$⇒x(2x - 1) + 5(2x - 1)$

$⇒(x + 5)(2x - 1)$

Hence , factorise

How to factorise any equation:-

• First split the middle term as we split like above 9x is replace by (10-1)x because 9 = 10 -1
• Then take common from all equation like we have taken x and 5.
• Then take brackets in one side and left one in another bracket.
