Add or Subtract to Simplify:

(5x + x2 - 4) - (4x - x2 + 6)

if that was the powe orf two it would have the small 2 at the top of one of the numbers so no.

Step-by-step explanation: if that was the power of two it would have the small 2 at the top of one of the numbers. also may i have brainliest?

2x to the second power + x-10

Step-by-step explanation:

Let's simplify step-by-step.

5x+x2-4 - (4x-x2+6)

Distribute the Negative Sign:

=5x+x2-4+-1 (4x-x2+6)

=5x+x2+-4+-1 (4x) + -1 (-x2) + (-1) (6)

=5x+x2+-4+-4x+x2+-6

Combine Like Terms:

=5x+x2+-4+-4x+x2+-6

= (x2+x2) + (5x+-4x) + (-4+-6)

=2x2+x+-10
