How many real number solutions does the equation have

y=-7x^2+6x+3=0

a. one solution

b. two solutions

c. no solution

d. infinite solutions

You have to find the discriminat b^2 - 4ac

If it is > 0, the function has two real solutions

if it is = 0, the function has one real solution

if it is <0, the function has no real solution

6^2 - 4 (7) (3) = 36 - 84 = - 48

Answer c. no solution
