WebSubtract the first from the second to obtain 8a+2b=2, or 4a+b=1. The derivative of your parabola is 2ax+b. When x=3, this expression is 7, since the derivative gives the slope of the tangent. So 6a+b=7. So we have. 6a+b=7. 4a+b=1. Subtract the second equation from the first to get 2a=6, or a=3. WebDivide -1, the coefficient of the x term, by 2 to get -\frac{1}{2}. Then add the square of -\frac{1}{2} to both sides of the equation. This step makes the left hand side of the equation a perfect square.
