Heya !!!
this is your answer.
Given :-
5x² -12x + 7 = 0.
We have to find two numbers a and b such that a+b = -12 and ab = 35.
By looking at the prime factors of 5×7.. ..
we get a and b as -5 and -7.
So.....
5x² -12x + 7 = 0.
5x² -7x - 5x + 7 = 0
x (5x-7) - 1(5x -7) = 0.
(x -1)(5x -7) = 0.
comparing with 0.....
x -15 = 0 or 5x -7= 0
x = 15. OR. x = 7/5.
Hence the zeroes of given polynomial are 15 and 7/5.
hope it helps
