Full solution

Q. Subtract 9x2+1 -9 x^{2}+1 from 7x4 -7 x-4 .\newlineAnswer:
  1. Write Polynomials: Write down the polynomials to be subtracted.\newlineWe have the first polynomial 7x4-7x - 4 and we need to subtract the second polynomial 9x2+1-9x^{2} + 1 from it.
  2. Set Up Subtraction: Set up the subtraction.\newlineTo subtract the second polynomial from the first, we change the signs of the second polynomial and then add it to the first polynomial.\newline(7x4)(9x2+1)(-7x - 4) - (-9x^{2} + 1)\newline=7x4+9x21= -7x - 4 + 9x^{2} - 1
  3. Combine Like Terms: Combine like terms. Since there are no like terms in this case, we simply write down the resulting polynomial. 9x27x419x^{2} - 7x - 4 - 1
  4. Simplify Constants: Simplify the constant terms. Combine 4-4 and 1-1 to get 5-5. 9x27x59x^{2} - 7x - 5
