Solve the quadratic equation 2 x 2 + 7 x + 6 = 0 by factorisation. Midpoint of AC = ( (1+x)/2 , (2+6)/2 ) = ((1+x)/2 , 4) Midpoint of BD = ((4+3)/2 , (5+y)/2 ) = (7/2 , (5+y)/2) Midpoint of AC and BD are the same; this implies (1+x)/2 = 7/2 and 4 = (5+y)/2. Q. x < −7 x < - 7. 查看解决方案步骤. Become a fan! Two numbers r and s sum up to -7 exactly when the average of the two numbers is \frac{1}{2}*-7 = -\frac{7}{2}. Q 4.Solve Using the Quadratic Formula x^2-7x-6=0 x2 − 7x − 6 = 0 x 2 - 7 x - 6 = 0 Use the quadratic formula to find the solutions.
