Solve -9x2 = 0

<---- Sponsored ads ------ >

Solution.

Given equation is -9x² = 0

Comparing it with the standard Form of Quadratic Equation ax² + bx + c = 0

a = -9, b = 0, c = 0

As we know, discriminant = b² - 4ac

Discriminant = (0)² - 4(-9)(0)

Discriminant = 0 - (0)

Discriminant = 0

Since discriminant = 0
Both roots are real and equal.

Using quadratic formula

Roots(x₁, x₂) =	−b ± √ b2 − 4ac
	2a

Roots(x₁, x₂) =	−b ± √ D
	2a

x₁ =	−b + √D
	2a

=	−(0) + √0
	2(-9)

=	0 + 0
	-18

= -0

x₂ =	−b - √D
	2a

=	−(0) - √0
	2(-9)

=	0 - 0
	-18

= -0

Roots: x₁ = , x₂ =

Sum of roots = -b/a

Sum of roots = -(0)/(-9)

Sum of roots = -0

Product of roots = c/a

Product of roots = (0)/(-9)

Product of roots = 0
