Answer:

x^{2} +11x-10

Step-by-step explanation:

(13x^{2} +9x-4)-(12x^{2} -2x+6)

Remove the brackets and multiply the minus sign through all the numbers in the second polynomial

13x^{2} +9x-4-12x^{2} +2x-6

Rearrange in the highest order

13x^{2} -12x^{2} +9x+2x-4-6

Simplify

x^{2} +11x-10

Multiply 4 times the numerator and the denominator:

4 × 1 = 4

4 × 4 = 16
