Question

find zeros of 3x^2-10x+7=0

Answer 1

let's start solving your question.
3x²-10x+7 = 0
By middle term splitting method,
3×7 = 21
So, 3x²-3x-7x+7 = 0
we can check it by,
   -3×-7 = 21
     and -3+(-7) = -10
Now,
make pairs of 3x²-3x-7x+7 = 0
       3x(x-1)-7(x-1) = 0
(3x-7) (x-1) = 0
3x-7 = 0               and      x-1 = 0   
x = 7/3                              x = 1
So, zeros are 7/3 and 1.
