Factorise
6x^2+29x + 20.​

Answer 1

Answer:

~ 6x^2 + 29x + 20

• [ splitting middle term , we get 24x + 5x = 29x & 24x × 5x = 120x^2 ; ( 6x^2 × 20 = 120x^2) ]

= 6x^2 + 29x + 20

= 6x^2 + 24x + 5x + 20

= 6x ( x + 4 ) + 5 ( x + 4 )

= ( x + 4 ) ( 6x + 5 ) ✓

Answer 2

Answer:

6x'2 + 29x + 20 = 0

6x'2 + 24x + 5x + 20 = 0

6x(x + 4) + 5(x + 4) = 0

(x + 4)(6x + 5) = 0

x + 4 = 0 or 6x + 5 = 0

x = -4 or x = -5/6
