1) {{{x^2}}}-6x+5=0
discrimant;
{{{(-6)^2}}}-4(1)(5)
36-20=16
The graph will have two solutions because the answer is positive.

2) {{{4y^2}}}-12y+9=0
{{{(-12)^2}}}-4(4)(9)
144-144=0
The graph will have one solution because the answer is 0.

3){{{3p^2}}}-p+2=0
{{{(-1)^2}}}-4(3)(2)
1-24=-23
The graph will have no solutions because the answer is negative.
