Question

Find the sum of these polynomials. (x^2 - 5x + 3) + (2x^2 - 3x - 7)

Answer 1

`3x^2 - 8x - 4`

Explanation:

This is a short and simple question, but it's good!

We are given the expression
`\left(x^2-5x+3\right)+\left(2x^2-3x-7\right)`, and simply being asked to combine like elements to simplify the expression. Take a look at the procedure below -

`\left(x^2-5x+3\right)+\left(2x^2-3x-7\right)` - Remove ( ),

`x^2-5x+3+2x^2-3x-7` - Add like elements,

`3x^2-5x-3x+3-7,\\3x^2-8x+3-7,\\` - And further simplify to derive solution

`Solution = 3x^2-8x-4`

Hope that helps!
