Question

factorise (3a-2b)²+3(3a-2b)-10​

Answer 1

3a-2b be x

Step-by-step explanation:

it becomes x² + 3x - 10

x² +5x -2x -10

x(x+5) -2(x+5)

(x+5) (X-2)

x=3a - 2b

therefore

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

Answer 2

Answer:

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

Step-by-step explanation:

If  (3a-2b) = c,

the equation becomes c²+3c-10

next step is to factorize

c²+3c-10 =    c²+5c-2c-10 =

c(c+5)-2(c+5) = (c+5)(c-2)

as c =3a-2b  

answer =  

(3a-2b+5)(3a-2b-2) or (3a-2b+5)  ×(3a-2b-2)
