Question

Factorise
a. 6x2 + 5 x -6

Answer 1

Answer:

6x2 – 5x – 25 = 0

Solution:

6x2 – 15x + 10x - 25 = 0

3x(2x – 5) + 5 (2x – 5)= 0

(2x – 5) (3x + 5) = 0

∴ 2x – 5 = 0 OR 3x + 5 = 0

∴ 2x = 5 or 3x = - 5

∴ x = 5 / 2 or x = - 5 / 3

Answer 2

Step-by-step explanation:

6x²+(9-4)x-6=0

6x²+9x-4x-6=0

3x(2x+3)-2(2x+3)=0

(2x+3)(3x-2)=0

2x+3=0

2x=3

x= -3/2

3x-2=0

3x=2

x=2/3
