Without solving the quadratic equation 3x2 - 2x - 1 = 0, find whether x = 1 is a solution (root) of this equation or not. please CORRECT me if i am Wrong so i think Substituting x = -1 in the given equation x2 - x + 1 = 0, we get (-1)2 - (-1) + 1 = 0

1 + 1 + 1 = 0

3 = 0; which is not true.

Therefore, x = -1 is not a solution of the given equation x2 - x + 1 = 0.

answer: dead jah

step-by-step explanation:

bullet + jah= dead jah

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.
