Question

find the zero of quadratic polynomial y square minus 5y plus 6​

Answer 1

Given,

${y^2-5y+6=0}$

Using factorisation method :-

${y^2 -3y-2y+6=0}$

${y(y-3)-2(y-3)=0}$

${(y-3)(y-2)=0}$

Now,

y - 3 = 0

y = 3

Again,

y - 2 = 0

y = 2

Therefore, y = 3,2

Answer 2

3 and 2 are the zeros
