C. (3x+1)(3x-2) 3x times 3x= 9x^2 and 3x times -1= -3x
2 times 3x= 6x and 2 times -1= -2
9x^2- 3x+6x-2
9x^2+3x-2
Hope I explain this more clearly for you.
I will tell you use a calculator and leave the answer there. Try the math see if you get it correct. If you don't tell me!
The answer is d because 4+8=12 and they are 4 units away from eachother:)
Assuming you meant the x2 as x squared, then:
(11x+4)(11x-4)
