using the roots of ax^2+bx+c=0( α and β)
please solve this
thank you
solve
acx^2-b(c+a)x+(c+a)^2=0
x = (a + c)(b ± √(b^2 - 4ac))/(2ac) =
= [(a + c)/c](b ± √(b^2 - 4ac))/(2a)
roots are
x_1 = [(a + c)/(ac)]·α
x_2 = [(a + c)/(ac)]·β
express (a + c)/(ac) = 1/a + 1/c
in terms of α and β
remember these relations
α + β = - b/a
α · β = c/a
