When we look at this thing for the first time, it looks like it's going to be a dog of a bear to solve, because 'q' is buried inside a squared term and a cubed term.

But this is why it's so important to learn that in math, you DON't immediately ignite your hair and go running around in circles as soon as you see the problem. The first thing you have to do every time is sit still, look at the problem, breathe air, and switch your brain into the 'ON' position.

Look at that big ugly fraction in the equation. Can it be simplified ? You betcha it can ! The quantity (q+r) is a factor of the numerator and denominator, so we can do some canceling.

Divide the top and the bottom of the fraction by (q+r)², and then the problem says . . .

p = (q+r)/12 + 4r

which is MUCH easier to unravel and solve for 'q' . Let's do this !

p = (q+r)/12 + 4r

Subtract (q+r)/12 from each side . . . p - (q+r)/12 = 4r

Subtract 'p' from each side . . . -(q+r)/12 = 4r - p

Multiply each side by -1 . . . (q+r)/12 = p - 4r

Multiply each side by 12 . . . (q+r) = 12p - 48r

Subtract 'r' from each side . . . q = 12p - 49r

Classify the following polynomials by degree and number of terms. 1. 4p3 + 2p2 + 19p - 5

motikmotik

Given:

The polynomial is:

$4p^3+2p^2+19p-5$

To find:

The degree and number of terms.

Solution:

Degree of a polynomial: It is the highest power of the variable.

Terms: Numbers, variables and product of them are called terms and they are separated by positive sign "+".

We have,

$4p^3+2p^2+19p-5$

In this polynomial, the variable is p and its highest power is 3. So, the degree of this polynomial is 3.

The given polynomial can be written as:

$4p^3+2p^2+19p+(-5)$

So, the terms in the given polynomial are $4p^3,2p^2,19p,-5$ .

Therefore, the degree of the given polynomial is 3 and the number of terms is 4.
