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.

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
