Solution for 3(3x+4)=-x(x-3) equation:


Simplifying
3(3x + 4) = -1x(x + -3)

Reorder the terms:
3(4 + 3x) = -1x(x + -3)
(4 * 3 + 3x * 3) = -1x(x + -3)
(12 + 9x) = -1x(x + -3)

Reorder the terms:
12 + 9x = -1x(-3 + x)
12 + 9x = (-3 * -1x + x * -1x)
12 + 9x = (3x + -1x2)

Solving
12 + 9x = 3x + -1x2

Solving for variable 'x'.

Combine like terms: 9x + -3x = 6x
12 + 6x + x2 = 3x + -1x2 + -3x + x2

Reorder the terms:
12 + 6x + x2 = 3x + -3x + -1x2 + x2

Combine like terms: 3x + -3x = 0
12 + 6x + x2 = 0 + -1x2 + x2
12 + 6x + x2 = -1x2 + x2

Combine like terms: -1x2 + x2 = 0
12 + 6x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-12' to each side of the equation.
12 + 6x + -12 + x2 = 0 + -12

Reorder the terms:
12 + -12 + 6x + x2 = 0 + -12

Combine like terms: 12 + -12 = 0
0 + 6x + x2 = 0 + -12
6x + x2 = 0 + -12

Combine like terms: 0 + -12 = -12
6x + x2 = -12

The x term is 6x.  Take half its coefficient (3).
Square it (9) and add it to both sides.

Add '9' to each side of the equation.
6x + 9 + x2 = -12 + 9

Reorder the terms:
9 + 6x + x2 = -12 + 9

Combine like terms: -12 + 9 = -3
9 + 6x + x2 = -3

Factor a perfect square on the left side:
(x + 3)(x + 3) = -3

Can't calculate square root of the right side.
