3x(x + 6) = -10 Enter your solution in the exact, most simplified form. If there are two solutions, write the answer using
the symbol.

See below

Step-by-step explanation:

To find the solution, we must first expand 3x(x+6) and move all terms onto one side.

3x²+18x=-10

3x²+18x+10=0

Since this equation is hard to factor, we will use the quadratic formula to get the solutions.

We know our values of A, B, C to plug into the quadratic equation.

A=3

B=18

C=10

(Ignore the capital A in the equation. It pops up when I use the ± sign.)

After you plug in the values of A, B, C into the equation, you get:

and

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.
