Question

Question 64. Determine whether the given
quadratic equations have equal roots and if so, find
the roots :
x² + 5x +5=0
​

Answer 1

• x2 +5x+5
• b2-4ac
• 25-20
• 5

Answer 2

x^2 + 5x + 5 = 0

here, a= 1, b = 5, c = 5

thus ,

D = b^2 - 4ac

= 5^2 - 4(1)(5)

= 25 - 20

= 5

No, this equation doesn't have any equal root
