If rhe discriminant of a quadratic equation is equal to -8 which statement describes the roots

Step-by-step explanation:

Given

Required

Determine the type of roots

Represent Discriminant with D; such that

D is calculated as thus

And it has the following sequence of results

When then the roots of the quadratic equation are real but not equal

When then the roots of the quadratic equation are real and equal

When then the roots of the quadratic equation are complex or imaginary

Given that ; This means that and base on the above analysis, we can conclude that the roots of the quadratic equation are complex or imaginary

you would need to know all the numbers that are on there

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
