Question

The quadratic equation ax² +bx + c = 0, if b² - 4ac = 0 , then two equal zeroes (roots) obtained ? (True/False)​

Answer 1

ANSWER : TRUE

Step-by-step explanation:

The quadratic equation ax² +bx + c = 0, if b² - 4ac = 0 , then two equal zeroes (roots) obtained.

FOR EXAMPLE,

x²- 4x + 4= 0

HERE ,

a = 1

b = -4

c = 4

→b²-4ac = (-4)²-4.4= 16-16=0.

VERIFICATION :

→ x = {-b ±√(b²-4ac)} / 2

→ x = (4±0)/2

→ x = 4/2,4/2

→ x = 2,2.

FROM THE ABOVE EXAMPLE, WE CAN SAY THAT : The quadratic equation ax² +bx + c = 0, if b² - 4ac = 0 , then two equal zeroes (roots) obtained .
