Full solution

Q. Subtract 7x2+8x3 -7 x^{2}+8 x-3 from 5x29x 5 x^{2}-9 x .\newlineAnswer:
  1. Write Polynomials: Write down the polynomials to be subtracted.\newlineThe first polynomial is 5x29x5x^{2}-9x, and the second polynomial to be subtracted from the first is 7x2+8x3-7x^{2}+8x-3.
  2. Set Up Problem: Set up the subtraction problem.\newline(5x29x)(7x2+8x3)(5x^{2}-9x) - (-7x^{2}+8x-3)
  3. Distribute Negative Sign: Distribute the negative sign across the second polynomial. \(5x^{22}9-9x) - (7-7x^{22}) - (88x) + 33\
  4. Combine Like Terms: Combine like terms.\newline(5x2+7x2)+(9x8x)+3(5x^{2} + 7x^{2}) + (-9x - 8x) + 3
  5. Perform Addition/Subtraction: Perform the addition and subtraction of like terms.\newline(5x2+7x2)=12x2(5x^{2} + 7x^{2}) = 12x^{2}\newline(9x8x)=17x(-9x - 8x) = -17x\newlineSo, the expression becomes:\newline12x217x+312x^{2} - 17x + 3
