Question

x^2 - 7x + k what is the simplification of this?​

Answer 1

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
