Factories:
6a(a – 2b) + 5b(a – 2b)

6a(a – 2b) + 5b(a – 2b)

Taking a – 2b as common from the whole, we get,

= (a – 2b)(6a + 5b).

Factories:

i. 14x³ + 21x⁴y – 28x²y²

ii. - 5 – 10t + 20t²

Factories:

i. x(x + 3) + 5(x + 3)

ii. 5x(x – 4) -7(x – 4)

iii. 2m(1 – n) +3(1 – n)

Factories:

x³(2a – b) + x²(2a – b)

Factories:

9a(3a – 5b) – 12a²(3a – 5b)

Factories:6a(a – 2b) + 5b(a – 2b)
