Question

Use the quadratic formula to solve the equation

x^2-3x+2=0

Answer 1

x= 1, 2

Explanation:

The quadratic formula is
`x=(-b+/-√(b^2-4ac) )/(2a)`. Here a=1, b=-3, and c=2.

Substitute and you'll have:

`x=(-b+/-√(b^2-4ac) )/(2a) =(3+/-√((-3)^2-4(1)(2)) )/(2(1))=(3+/-√(9-8) )/(2))`

`(3+/-√(1) )/(2)=(3+/-√(1) )/(2)=(3+/-1 )/(2)= 2 , 1`
