Solution for (v+9)(v+10)= equation:


Simplifying
(v + 9)(v + 10) = 0

Reorder the terms:
(9 + v)(v + 10) = 0

Reorder the terms:
(9 + v)(10 + v) = 0

Multiply (9 + v) * (10 + v)
(9(10 + v) + v(10 + v)) = 0
((10 * 9 + v * 9) + v(10 + v)) = 0
((90 + 9v) + v(10 + v)) = 0
(90 + 9v + (10 * v + v * v)) = 0
(90 + 9v + (10v + v2)) = 0

Combine like terms: 9v + 10v = 19v
(90 + 19v + v2) = 0

Solving
90 + 19v + v2 = 0

Solving for variable 'v'.

Factor a trinomial.
