Answer:
x = - 8, x = - 4
Step-by-step explanation:
Given
x² + 15x + 30 = 3x - 2 ( subtract 3x - 2 from both sides )
x² + 12x + 32 = 0 ← in standard form
Consider the factors of the constant term (+ 32) which sum to give the coefficient of the x- term (+ 12)
The factors are + 8 and + 4 , since
8 × 4 = + 32 and 8 + 4 = + 12 , then
(x + 8)(x + 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 8 = 0 ⇒ x = - 8
x + 4 = 0 ⇒ x = - 4
The answer would be 20 because if you multiply the entire equation by five you would get 5n+n=120. Then if you solve that smaller equation it gives you 20.

I’ll teach you how to solve 3.26d+9.75d-2.65
——————————————-
3.26d+9.75d-2.65
Collect like terms by adding their coefficients:
(3.26+9.75)d-2.65
Add the numbers:
3.26+9.75= 13.01
13.01d-2.65
Your Answer Is 13.01d-2.65
