Answer:
156x²
Step-by-step explanation:
6×2x=12x+1=13x
2×5x=10x+2=12x
you multiply those numbers together because if the is no sign like addition or subtraction its considered multiplication so you multiply 13x by 12x
and you will get: 156x²
cuz also is x is multiplied by x it turns into a power/index
