You can also see that the midpoint of r and s corresponds to the axis of symmetry of the parabola represented by the quadratic equation y=x^2+Bx+C.

Algebra. Solve by Factoring x^2+10x+21=0. x2 + 10x + 21 = 0 x 2 + 10 x + 21 = 0. Factor x2 + 10x+21 x 2 + 10 x + 21 using the AC method. Tap for more steps... (x+3)(x+ 7) = 0 ( x + 3) ( x + 7) = 0. If any individual factor on the left side of the equation is equal to 0 0, the entire expression will be equal to 0 0. x+3 = 0 x + 3 = 0.So you'd set the first set of parentheses like so: (x-2)=0. Then to isolate "x", you would add 2 to both sides to get x=2. Then, You would set the other set of parentheses to zero, like so: (x+4)=0. To isolate "x", you would subtract 4 from both sides to get x=-4. So, your final answer would be x=2 or x=-4. Hope this helped you out.X2+10X+21=0 Sumamos todos los números y todas las variables.
