i) Multiply the highest degree and lowest degree coefficient i.e. a and c
ii) Add or subtract two numbers to find the coefficient b such that multiplication of these two give the multiplication from step i)
iii) write in factorization form by taking common part out from the polynomial
Step 2
Given polynomial
15x2+7x4
15x2+12x5x4..[12(5)=15(4)]
3x(5x+4)1(5x+4)
