Given function :
Splitting terms to factor it out.
Making it into groups
(5x^3-x^2) + (-5x^2+x) + (-60x+12)
Factoring out GCF of each group.
Factoring x^2-x-12 into (x+3)(x-4)
Applying zero product rule.
5x-1 =0
x+3=0 and
x-4= 0
On solving
x = 1/5 , x=-3 and x=4.
Therefore, zeros of the given function are .

________________________________
• To solve Questions of type 11 we need to simplify the equation by using mathematical operations !!
• To solve Questions of type ( 13 , 15 and 17 ) we try to make the bar numeral to come other side of decimal
° and by subtracting we get the required fraction !!
