Answer:
Simplified: -21-98t
Factored: -7(14t+3)
Step-by-step explanation:
The given expresion is:
14-28t-5(7+10t)
We expand the parenthesis to get:

We group like terms to get:

We combine similar terms to get:

We now factor to obtain:

The value of the differential with respect to x is -xy/x²+ay
<h3>Implicit differentiation</h3>
Given the following function
x²y +ay² = b
We are to differentiate implicitly with respect to x
x²dy/dx + 2xy + 2aydy/dx = 0
(2x²+2ay)dy/dx = -2xy
dy/dx = -xy/x²+ay
Hence the value of the differential with respect to x is -xy/x²+ay
