Simplify:(D2 + 4D + 5) * y = 0

Answer»
Create separate equations

(d² + 4d + 5)y = 0

(d² + 4d +5) = 0

y = 0

(D2 + 4D + 5) * y = 0

Reorder the terms:

(5 + 4D + D2) * y = 0

Reorder the terms for easier multiplication:

y(5 + 4D + D2) = 0

(5 * y + 4D * y + D2 * y) = 0

(5y + 4yD + yD2) = 0

Solving:

5y + 4yD + yD2 = 0

Solving for variable 'y'.

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

Factor out the Greatest Common Factor (GCF), 'y'.

y(5 + 4D + D2) = 0
