What is the discriminant? What does it tell you about the types of solutions you can have?

Step-by-step explanation:

ax² + bx + c = 0

Discriminant D = [ - b ± √(b² - 4ac) ] / 2a

If D > 0, then quadratic equation has 2 real roots ;

If D = 0, then quadratic equation has 1 real root ;

If D < 0, then quadratic equation has 0 real roots .

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25
