Hi there!
When we have an equation standard form... [tex]a {x}^{2} + bx + c = 0[/tex] ...the formula of the discriminant is D = b^2 - 4ac
When D > 0 we have two real solutions D = 0 we have one real solutions D < 0 we don't have real solutions
1.) Find the value of the discriminant and the the number of real solutions of x^2-8x+7=0
Plug in the values from the equation into the formula of the discriminant
