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 ≈

-6.3Therefore the solutions are 1.3 and -6.3.
