Use the discriminant to determine the number of solutions for the quadratic equation.

2 real solutions

Step-by-step explanation:

y = -x^2 + 3x + 5

First find the the discriminant:

using b² - 4(a)(b)

(3)²- 4(-1)(5)

=9+20

=29

since the discriminant is more than 0, there are 2 real solutions

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
