Factorise: (2a-3b)(p+q)+(a-b)(p+q)

Question

My maths I need help on this beacuse i cant calculate well enough

Answer 1

The factor that the each term in the polynomial have in common is  (p + q).  We can use this as the GCF.

 

 

(p + q)((2a - 3b) + (a - b)) =

 

(p + q)(3a - 5b)

 

 

a, b, c, and d are unclear, but for e, the GCG is 3.  Use the GCF to factor out the polynomial.
