1.

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

Answer»

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
