What is the polynomial form?
qaws [65]
Polynomials are simply functions that you see all the time

A second degree polynomial would look like:
y = ax^2 + bx + c
That is because the largest power is to the 2.

A third degree polynomial would be raised to the third power when it's the biggest number:
y = ax^3 + bx^2 + cx + d

The a, b, c, and d are just variables for any number

Answer:

\frac{3}{4}(m+n)-\frac{1}{4}(m-n) = \frac{14}{24}

Step-by-step explanation:

Given

\frac{3}{4}(m+n)-\frac{1}{4}(m-n);m=\frac{1}{2},n=\frac{1}{3}

Required

Solve

To do this, we simply substitute values of m and n in the given expression

\frac{3}{4}(\frac{1}{2}+\frac{1}{3})-\frac{1}{4}(\frac{1}{2}-\frac{1}{3})

Evaluate the brackets

\frac{3}{4}(\frac{3 + 2}{6})-\frac{1}{4}(\frac{3-2}{6})

\frac{3}{4}(\frac{5}{6})-\frac{1}{4}(\frac{1}{6})

Open Brackets

\frac{15}{24} - \frac{1}{24}

Take LCM

\frac{15 - 1}{24}

\frac{14}{24}

Hence:

\frac{3}{4}(m+n)-\frac{1}{4}(m-n) = \frac{14}{24}
