130
3x2+13x-10 = (3x-2)(x+5) when factored
x2 + 13x = -30 ∴ x2 + 13x + 30 = 0 ∴ (x + 3)(x + 10) = 0 ∴ x ∈ {-3, -10}
(x + 1)(3x + 10)
x2 - 13x + 30 = (x - 3)(x - 10). In case you are provided with a list that you forgot to include with your question, then any of the following is a possible factor: x - 3; x - 10; 3 - x; or 10 - x.
13x + 15 = 11x - 5 2x = -20 x = -10

13x+27=3x+32 Reorder 13x-3x=32-27 Simplify 10x=5 Simplify x=5/10 Simplify x=1/2 Answer
13x-10x = 3
13x - 4x = 9
X^2 - 13X + 30 = 0 (X-3)(X-10) easy inspection problem
(13x)2 = 169x2
(x - 10)(x - 3)
