(ii)x²-9x-22
(iii)2x²-7x+6
(iv)3x²+11x+6
​

Answer 1

Step-by-step explanation:

+ (-56 – 5). =7 +(-61). = -54. 12-2632). _12 _(-4), 3. - 54. 1. 3. -2. G. 2x² - 7x + 2; solve when x = -3. Substitute x with -3 and solve. (6) 12.

Answer 2

Step-by-step explanation:

Hey mate, if you want me to factories then this will be the answers:

i) x²+5x+6                Product= 6     Sum= 5

= x²+ 2x + 3x + 6    Number is= 2& 3

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

∴ The factors are (x+3)  (x+2)

iii) 2x²-7x+6             Product= 12   Sum= -7

= x² -4x - 3x +6        Numbers are= -4, -3

= 2x ( x-2) -3 (x -2)

∴ The factors are (2x - 3)  (x-2)

iv) 3x²+11x+6         Product = 18      Sum= 11

= 3x²+ 9x + 2x+ 6      Numbers are= 9, 2

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

∴ The factors are (3x+2)  &  (x+3)

Hope this helps you
