1 2/3 x 2 3/5
1 2/3 x 2 3/5-Answer We know that if m and n are the roots of a quadratic equation ax2 bxc =0, then the sum of the roots is (mn) and the product of the roots is (mn) And then the quadratic equation becomes x2 −(mn)xmn = 0 Here, it is given that the roots of the quadratic equation are m = (2 33 1 x 2 3 2 3 x 2 3 3 1 x 2 3 4 3 3 1 x 2 3 1 B 3 1 x 2 3 2 3 3 2 3 3 3 2 3 1 A from MATH 123 at Faculdade SenaiCetiqt SENAICETIQT
The point B is where the line cuts the yaxisWe can let the coordinates of B be (0,b) so that b, called the yintercept, indicates how far above the xaxis B lies (This notation conflicts with labeling the sides of a triangle a, b, and c, so let's not label the sides right now) You can see that the point 1 unit to the right of the origin is labeled 1, and its coordinates, of course, are1 2 1 RESOLUCIÓN 13 1 3 1 8 A 2 B 1 C 3 D E 9Efectuar 3 57 3 2 x 75 6 A 1 B 2 C from MATH 123 at Faculdade SenaiCetiqt SENAICETIQTThe entire trig table below shows approximate values for
