Answer: x=−1 or x=1 or x=−2 or x=3
Step-by-step explanation: Step 1: Factor left side of equation.
(x+1)(x−1)(x+2)(x−3)=0
Step 2: Set factors equal to 0.
x+1=0 or x−1=0 or x+2=0 or x−3=0
x=−1 or x=1 or x=−2 or x=3
Answer:
13x^8 + 4x^5 - 16x^2
Step-by-step explanation:
Standard form is just rearranging each group of numbers so that the group with the most exponents on the variables is at the beginning. So it's basically least to greatest but with exponents. Hope this helped!
The general solution, y(t), which solves the problem by the method of integrating factors is; y = ¹/₂₁t⁴ + (1/t)c₁t^(⁴/₅)
<h3>How to solve differential equations?</h3>
We want to find the general solution of;
5t(dy/dt) + y = t⁴
We will divide through by 5t to get;
(dy/dt) + y/5t = t³/6
Using Integration factor, we have;
u(t) = e^∫(¹/₅t) dt = t^(¹/₅)
Thus, we now have;
[t^(¹/₅)](dy/dt) + [t^(¹/₅)]y/5t = [t^(¹/₅)]t³/6
Completing this with a differential calculator gives us the general solution as;
y = ¹/₂₁t⁴ + (1/t)c₁t^(⁴/₅)
