solve it fast plz
Tomorrow is my exam

Answer 1

Answer:

$1) = > 2 {x}^{2} + 7x + 3 \\ \\ = > 2 {x}^{2} + (6 + 1)x + 3 \\ \\ = > 2{x}^{2} + 6x + x + 3 \\ \\ = > 2x(x + 3) + 1(x + 3) \\ \\ = > (x + 3)(2x + 1) \\ \\ \\ 2) = > {y}^{2} - 5y + 6 \\ \\ = > {y}^{2} - (2 + 3)y + 6 \\ \\ = > {y}^{2} - 2y - 3y + 6 \\ \\ = > y(y - 2) - 3(y - 2) \\ \\ = > (y - 2)(y - 3)$

Answer 2

$\huge\tt\pink{Solution:-}$

1 ) 2x² + 7x + 3

= 2x² +6x + x + 3

= (2x² + 6x) + (x + 3)

= 2x ( x + 3) + 1 (x + 3)

= ( 2x + 1 ) ( x + 3 )

2) y² - 5y + 6

= y² - 2y - 3y + 6

= ( y² - 2y ) - ( 3y - 6 )

= y ( y - 2) - 3 ( y - 2 )

= (y - 3) (y - 2)
