Factor the expression

20k + 50

-2.5

Step-by-step explanation:

Simplifying

20k + 50 = 0

Reorder the terms:

50 + 20k = 0

Solving

50 + 20k = 0

Solving for variable 'k'.

Move all terms containing k to the left, all other terms to the right.

Add '-50' to each side of the equation.

50 + -50 + 20k = 0 + -50

Combine like terms: 50 + -50 = 0

0 + 20k = 0 + -50

20k = 0 + -50

Combine like terms: 0 + -50 = -50

20k = -50

Divide each side by '20'.

k = -2.5

10(2k+5)
