Q. Solve the quadratic by factoring.\newlinex2+8x17=7x5 x^{2}+8 x-17=7 x-5 \newlineAnswer: x= x=
  1. Write Standard Form: Write the quadratic equation in standard form.\newlineTo solve the quadratic by factoring, we need to have it in the form ax2+bx+c=0ax^2 + bx + c = 0. We start by moving all terms to one side of the equation.\newlinex2+8x17=7x5x^2 + 8x - 17 = 7x - 5\newlineSubtract 7x7x from both sides:\newlinex2+8x7x17+5=0x^2 + 8x - 7x - 17 + 5 = 0\newlinex2+x12=0x^2 + x - 12 = 0
  2. Factor Quadratic Equation: Factor the quadratic equation.\newlineWe need to find two numbers that multiply to 12-12 and add up to 11 (the coefficient of xx).\newlineThe numbers that satisfy these conditions are 44 and 3-3 because:\newline4×(3)=124 \times (-3) = -12\newline4+(3)=14 + (-3) = 1\newlineSo we can factor the quadratic as:\newline(x+4)(x3)=0(x + 4)(x - 3) = 0
  3. Solve for x: Solve for x.\newlineTo find the solutions to the equation, we set each factor equal to zero and solve for xx.\newlineFirst factor:\newlinex+4=0x + 4 = 0\newlinex=4x = -4\newlineSecond factor:\newlinex3=0x - 3 = 0\newlinex=3x = 3
