Question

How do you find the zeros of f(x)=5x2−25x+30?

Answer 1

Solution:

Given f(x) = 5x²-25x+30

To find zeroes of f(x) , we must take f(x) = 0

=> 5x²-25x+30=0

Divide each term by 5 ,we get

=> x²-5x+6=0

Splitting the middle term,we get

=> x²-3x-2x+6=0

=> x(x-3)-2(x-3)=0

=> (x-3)(x-2)=0

=> x-3=0 or x-2=0

=> x = 3 or x = 2

Therefore,

2,3 are two zeroes of f(x)
