Question

Factorise the following polynomials.
1. a(f+g)+b(f+g)​

Answer 1

Answer:

In the same way as you could factor trinomials on the form of

x2+bx+c

You can factor polynomials on the form of

ax2+bx+c

If a is positive then you just proceed in the same way as you did previously except now

ax2+bx+c=(x+m)(ax+n)

wherec=mn,ac=pqandb=p+q=am+n

Answer 2

answer=(f+g)+(a+b)

because there regrouping method has applied so according to the method we have to first take out common (i.e f+g) and then the left one (i.e. a+b)and then came (a+b)+(f+g)
