Select the best answer from the choices provided

B

Step-by-step explanation:

3x² + 5x + 1 = 0

Quadratic formula: (-5 ± (√(25 - 4*3)))/6

From just this, we can say that B is the answer without any further work, since

B.

Step-by-step explanation:

We have been given an equation . We are asked to solve for x.

We will use quadratic formula to solve our given problem as our given equation is in form .

Substitute given values:

Therefore, the solutions for our given equation are and option B is the correct choice.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

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.
