Solve this quadratic equation using the quadratic formula. 2x2 - 10x + 7 = 0

Step-by-step explanation:

2x^2-10x+7         A=1, B=-10. C=7

-(-10)±√-10^2-4(1)(7)

2(1)

10±√100-28

10±8.485281374

         2

10+8.485281374 =9.24

             2

10-8.485281374 =0.76

          2

x= 5/ 2 + 1/2  √11

or  x= 5/ 2 + −1/ 2 √11

step-by-step explanation:

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
