Simplifying
4x + 3 = x2 + 4x + 3
Reorder the terms:
3 + 4x = x2 + 4x + 3
Reorder the terms:
3 + 4x = 3 + 4x + x2
Add '-3' to each side of the equation.
3 + -3 + 4x = 3 + 4x + -3 + x2
Combine like terms: 3 + -3 = 0
0 + 4x = 3 + 4x + -3 + x2
4x = 3 + 4x + -3 + x2
Reorder the terms:
4x = 3 + -3 + 4x + x2
Combine like terms: 3 + -3 = 0
4x = 0 + 4x + x2
4x = 4x + x2
Add '-4x' to each side of the equation.
4x + -4x = 4x + -4x + x2
Combine like terms: 4x + -4x = 0
0 = 4x + -4x + x2
Combine like terms: 4x + -4x = 0
0 = 0 + x2
0 = x2
Solving
0 = x2
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1x2' to each side of the equation.
0 + -1x2 = x2 + -1x2
Remove the zero:
-1x2 = x2 + -1x2
Combine like terms: x2 + -1x2 = 0
-1x2 = 0
Divide each side by '-1'.
x2 = 0
Simplifying
x2 = 0
Take the square root of each side:
x = {0}
