Question

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

Answer 1

Answer:

$3x^2 - 8x - 4$

Step-by-step 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!
