Answer:
Simplifying
x2 + -7x + k = 0
Reorder the terms:
k + -7x + x2 = 0
Solving
k + -7x + x2 = 0
Solving for variable 'k'.
Move all terms containing k to the left, all other terms to the right.
Add '7x' to each side of the equation.
k + -7x + 7x + x2 = 0 + 7x
Combine like terms: -7x + 7x = 0
k + 0 + x2 = 0 + 7x
k + x2 = 0 + 7x
Remove the zero:
k + x2 = 7x
Add '-1x2' to each side of the equation.
k + x2 + -1x2 = 7x + -1x2
Combine like terms: x2 + -1x2 = 0
k + 0 = 7x + -1x2
k = 7x + -1x2
Simplifying
k = 7x + -1x2
