Question
Solve x2 - 12x + 30 = 0 using formula.
options:
a) -6 + √6, -6 - √6
b) 6 + √6, -6 - √6
c) -6 + √6,6 - √6
d) 6+ √6, 6 - √6​

Answer 1

Answer:

d)6+ √6, 6 - √6

Step-by-step explanation:

by formula,

x=[-b+- root(b^2-4ac) }/ 2a

here a=1,b= -12, c=30

by substituting these values we get

x=6+ √6, 6 - √6
