Q. Simplify the following expression completely.\newlinex216x+63x2+3x70 \frac{x^{2}-16 x+63}{x^{2}+3 x-70} \newlineAnswer:
  1. Factor Numerator and Denominator: Factor the numerator and the denominator.\newlineThe numerator x216x+63x^2 - 16x + 63 can be factored into (x7)(x9)(x - 7)(x - 9) because 7×9=637 \times 9 = 63 and 7+9=167 + 9 = 16.\newlineThe denominator x2+3x70x^2 + 3x - 70 can be factored into (x+10)(x7)(x + 10)(x - 7) because 10×7=7010 \times -7 = -70 and 107=310 - 7 = 3.
  2. Simplify by Canceling Common Factors: Simplify the expression by canceling out common factors. The common factor in the numerator and the denominator is (x7)(x - 7). So, we cancel out (x7)(x - 7) from both the numerator and the denominator. The simplified expression is x9x+10\frac{x - 9}{x + 10}.
