Answer 1

$\huge{\underline{\underline{\mathfrak{Answer}}}}$

$= > 2 {x}^{2} + x - 45$

$= > 2 {x}^{2} + 10x - 9x - 45$

$= > 2x(x + 5) - 9(x + 5)$

$= > (2x - 9)(x + 5)$

Answer 2

Answer

(x + 5)(2x - 9)

Step-by-step explanation:

2x^2 + x - 45

= 2x^2 + 10x - 9x -45

= 2x(x + 5) -9(x+5)

=(x + 5)(2x - 9)

Ans

if you want the zeroes for x :

(x + 5)(2x - 9)=0

=> x + 5 = 0                ,  2x - 9 = 0

=> x = -5                     , 2x = 9

=> x = -5                     , x = 9/2

Therefore, the required values of x are -5 and 9/2
