Question

can you solve this useing quadratic formula?? show me! x^2-11x+8=0

Answer 1

x = \[-b ± \sqrt{b ^{2} - 4ac}\over2a\]
a = 1
b = -11
c = 8
Just plug in numbers.

Answer 2

that looks like an alien lang. to me :/

Answer 3

Just plug in the numbers for the letters.
\[-(-11) ± \sqrt{(-11)^{2} - 4(1)(8)}\over2(1)\]
\[11 ± \sqrt{121 - 32}\over 2\]
\[11 ± \sqrt{89}\over2\]
Now you can just approximate or if you want an exact answer, just leave it like that.
