Solution for -4x^2+(-7x)+(-4)+3x^2+8x+(-4)= equation:


Simplifying
-4x2 + (-7x) + (-4) + 3x2 + 8x + (-4) = 0
-4x2 + (-7x) + -4 + 3x2 + 8x + (-4) = 0
-4x2 + (-7x) + -4 + 3x2 + 8x + -4 = 0

Reorder the terms:
-4 + -4 + (-7x) + 8x + -4x2 + 3x2 = 0

Combine like terms: -4 + -4 = -8
-8 + (-7x) + 8x + -4x2 + 3x2 = 0

Combine like terms: (-7x) + 8x = 1x
-8 + 1x + -4x2 + 3x2 = 0

Combine like terms: -4x2 + 3x2 = -1x2
-8 + 1x + -1x2 = 0

Solving
-8 + 1x + -1x2 = 0

Solving for variable 'x'.

Begin completing the square.  Divide all terms by
-1 the coefficient of the squared term: 

Divide each side by '-1'.
8 + -1x + x2 = 0

Move the constant term to the right:

Add '-8' to each side of the equation.
8 + -1x + -8 + x2 = 0 + -8

Reorder the terms:
8 + -8 + -1x + x2 = 0 + -8

Combine like terms: 8 + -8 = 0
0 + -1x + x2 = 0 + -8
-1x + x2 = 0 + -8

Combine like terms: 0 + -8 = -8
-1x + x2 = -8

The x term is -1x.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1x + 0.25 + x2 = -8 + 0.25

Reorder the terms:
0.25 + -1x + x2 = -8 + 0.25

Combine like terms: -8 + 0.25 = -7.75
0.25 + -1x + x2 = -7.75

Factor a perfect square on the left side:
(x + -0.5)(x + -0.5) = -7.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
