Equation:
Solution for x^2+kx+16=0 equation:
Simplifying
x2 + kx + 16 = 0
Reorder the terms:
16 + kx + x2 = 0
Solving
16 + kx + x2 = 0
Solving for variable 'k'.
Add '-16' to each side of the equation.
16 + kx + -16 + x2 = 0 + -16
Reorder the terms:
16 + -16 + kx + x2 = 0 + -16
Combine like terms: 16 + -16 = 0
0 + kx + x2 = 0 + -16
kx + x2 = 0 + -16
Combine like terms: 0 + -16 = -16
kx + x2 = -16
Add '-1x2' to each side of the equation.
kx + x2 + -1x2 = -16 + -1x2
Combine like terms: x2 + -1x2 = 0
kx + 0 = -16 + -1x2
kx = -16 + -1x2
Divide each side by 'x'.
k = -16x-1 + -1x
Simplifying
k = -16x-1 + -1x
