Q. Let x1x_1 and x2x_2 be solutions to the equation shown, with x1>x2x_1 > x_2. What is the value of x1+x2x_1+x_2? 16x28x3=016x^2-8x-3=0
  1. Recognize Equation Type: Recognize that the equation 16x28x3=0 16x^2 - 8x - 3 = 0 is a quadratic equation in the standard form ax2+bx+c=0 ax^2 + bx + c = 0 , where a=16 a = 16 , b=8 b = -8 , and c=3 c = -3 .
  2. Sum of Roots Formula: Recall the sum of the roots formula for a quadratic equation ax2+bx+c=0 ax^2 + bx + c = 0 , which states that the sum of the roots x1+x2 x_1 + x_2 is equal to ba -\frac{b}{a} .
  3. Apply Formula: Apply the sum of the roots formula to the given equation. Substitute a=16 a = 16 and b=8 b = -8 into the formula to find x1+x2 x_1 + x_2 .
  4. Calculate Sum: Calculate the sum of the roots using the formula x1+x2=816 x_1 + x_2 = -\frac{-8}{16} .
  5. Simplify Fraction: Simplify the fraction to get x1+x2=12 x_1 + x_2 = \frac{1}{2} .
