Can someone simplify 2x² + 3x + 5x² - 2x + x² + x

5x² - 5x +12 - 3x² +2(x-5)
This can only be simplified because it is not equated to any value.

STEP 1=>Expand 2(x-5)
=2x-10

We now have,
5x² - 5x +12 - 3x² +2x - 10

STEP 2=>Collect like terms. Where all elements of equal power are together irrespective of the mathematical sign.

5x²-3x²-5x+2x+12 -10

STEP 3=>Add and subtract where necessary.

2x² - 3x +2

Where ax² +bx +c is known a quadratic expression.

Thus, 2x² - 3x +2 is a quadratic expression.

It's advisable to stop at this stage because simplify further will seem kinda difficult cos it might lead to complex root when equated to zero.

NOTE:We can find the value of x provided the expression I equated to 0 or any value. But the question u asked has nothing to do with equality sign. But if it's equal to a value, then we solve the quadratic equation which produces 2 values of x.
