Answer 2

Do you know PEMDAS ?

Answer 3

To add polynomials you add their similar terms.

Similar terms are monomials that are exactly alike or are the same except for their numerical coefficients.

$$\Huge (10x^2− 8x − 1) + (4x^2− 8x − 5)$$

$$\Huge 10x^2− 8x − 1+ 4x^2− 8x − 5$$

$$\Huge 10x^2+ 4x^2− 8x -8x -1− 5$$

$$\Huge (10+4)x^2 -(8+8)x-6$$

$$\Huge 14x^2-16x-6$$
