Which are the solutions of x2 = –5x + 8?

As exact answers:

 and  

As decimal answers:

x = -6.2749172 ≈-6.3

x = 1.27491722 ≈  1.3

Step-by-step explanation:

For quadratic equations, you can use the quadratic formula. Rearrange the equation to standard from, which is ax² + bx + c = 0.

x² = –5x + 8

x² + 5x - 8 = 0

State the values for "a", "b" and "c",

a = 1; b = 5; c = -8

           (Ignore the Â, it's a formatting error)

          Simplify

              Two negatives make a positive

Split the equation at the ± for plus and minus:

 = 1.27491722 ≈ 1.3

 = -6.2749172 ≈ -6.3

Therefore the solutions are 1.3 and -6.3.

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
