Question

If the discriminant of an equation is zero which of the folllwing is true of the equation?

Answer 1

Answer: one real solution

Step-by-step explanation:

Answer 2

Step-by-step explanation:

the discriminant of an equation, ax^2 + bx + c= 0 is

b^2 - 4ac

if b^2 - 4ac = 0

the equation will have equal roots therby being perfect

conclusion:

if the discriminant of an equation is zero

• the equation will have two roots
• the equation will have one real solution
• the curve of the equation will touch the x-axis at only one point
• the equation will be a perfect square
