$\dfrac 56 x + \dfrac25 y - \dfrac14 x + \dfrac3{10} y$

First, combine like terms:

$\left(\dfrac 56 - \dfrac14\right) x + \left(\dfrac25 + \dfrac3{10}\right)y$

Now just simplify the coefficients of x and y. We do this by converting each pair of fractions to ones with a common denominator. Then we can combine them easily.

$\dfrac56 - \dfrac14 = \dfrac56\cdot\dfrac22 - \dfrac14\cdot\dfrac33 = \dfrac{5\cdot2}{6\cdot2} - \dfrac{1\cdot3}{4\cdot3} = \dfrac{10}{12} - \dfrac3{12} = \dfrac{10-3}{12} = \dfrac7{12}$

$\dfrac25 + \dfrac3{10} = \dfrac25\cdot\dfrac22 + \dfrac3{10} = \dfrac{2\cdot2}{5\cdot2} + \dfrac3{10} = \dfrac4{10} + \dfrac3{10} = \dfrac{4+3}{10} = \dfrac7{10}$

So the simplified expression would be

$\dfrac7{12} x + \dfrac7{10} y$

Simplify the expression in picture

Answer:

6x^2 + -10

Step-by-step explanation:

Hi there! I'm glad I was able to help you answer this polynomial expression!

All we're really doing to solve is combine like terms.

(5x^2+2) - (-4x^2+7) + (-3x^2-5) = _____________

5x^2 + 2 + 4x^2 + -7 + -3x^2 + -5

(5x^2 + 4x^2 + -3x^2) + (2 + -7 + -5)

6x^2 + -10

The terms that have x^2 at the end are in bold letters so you know what we're combining them - the other numbers are the separate like terms.

Simplified, our answer is 6x^2 + -10.

I hope this helped you! Leave a comment below if you have any further questions! :)
