2x(x-3)=5-(x*x-4)

Solution for 2x(x-3)=5-(x*x-4) equation:

Simplifying
2x(x + -3) = 5 + -1(x * x + -4)

Reorder the terms:
2x(-3 + x) = 5 + -1(x * x + -4)
(-3 * 2x + x * 2x) = 5 + -1(x * x + -4)
(-6x + 2x2) = 5 + -1(x * x + -4)

Multiply x * x
-6x + 2x2 = 5 + -1(x2 + -4)

Reorder the terms:
-6x + 2x2 = 5 + -1(-4 + x2)
-6x + 2x2 = 5 + (-4 * -1 + x2 * -1)
-6x + 2x2 = 5 + (4 + -1x2)

Combine like terms: 5 + 4 = 9
-6x + 2x2 = 9 + -1x2

Solving
-6x + 2x2 = 9 + -1x2

Solving for variable 'x'.

Reorder the terms:
-9 + -6x + 2x2 + x2 = 9 + -1x2 + -9 + x2

Combine like terms: 2x2 + x2 = 3x2
-9 + -6x + 3x2 = 9 + -1x2 + -9 + x2

Reorder the terms:
-9 + -6x + 3x2 = 9 + -9 + -1x2 + x2

Combine like terms: 9 + -9 = 0
-9 + -6x + 3x2 = 0 + -1x2 + x2
-9 + -6x + 3x2 = -1x2 + x2

Combine like terms: -1x2 + x2 = 0
-9 + -6x + 3x2 = 0
