Question

18bx²+18bx-20b factorise​

Answer 1

Step-by-step explanation:

18bx²+18bx-20b

18bx²-12bx+30bx-20b

6bx(3x-2)+10b(3x-2)

(3x-2)(6bx+10b)

2b(3x-2)(3x+5)

Answer 2

18bx²+18bx-20b

b(18x²+18x-20)

2b(9x²+9x-10)

2b(9x²-9x+10x-10)

2b[9x(x-1)+10(x-1)]

2b[(9x+10) (x-1)]

2b(9x+10) and 2b(x-1)
