Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. 4x^2 + 20x + 25 = 0

D =  0

one real solution

Step-by-step explanation:

Given equation is :

4x²+20x+25=  0

general quadratic equation is ax²+bx+c =  0

the formula to find discriminant is :

D =  b²-4ac

If D =  0 then quadratic equation will have one real solution.

comparing given equation with general equation,we get

a =  4 , b=  20 and c =  25

putting above values in formula of discriminant,we get

D=  (20)²-4(4)(25)

D=  400-400

D=  0

If D =  0 then quadratic equation will have one real solution.

hence , given equation have one real solution.
