Answer:
The first blank is 81+9=x-1
The second blank is 9x+3=x^2-1
Step-by-step explanation:
For the first part, you must set up the equation (9x+3)^2 then you must multiply the exponent to the inside exponents + next, simplify.
81+9=x-1
For part two, set up equation. Then simplify 9x+3=
-3/4
-5/4 + 2/4 = -3/4
