Question
Find the value of discriminant.
2y2 – 5y + 10 = 0
Solution
2y2 – 5y + 10 = 0 Comparing the given equation with ax2 + bx + c = 0
a = 2, b = -5 and c = 10
So, the discriminant b2 - 4ac = (-5)2 - 4 × 2 × 10
= 25 - 80
= -55

If a, b, care in continued proportion, then show that `(a + b)^2/(ab) = (b + c)^2/(bc)`.
Since a, b, c are in continued proportion
∴ `a/b = square/square` = k(say)
⇒ b = `square`, a = `square` = `square`.k = `square`.k2
Now, L.H.S. = `(a + b)^2/(a.square) = (square + square)^2/(square*square)`
= `(squarek^2(k + 1)^2)/(square*square)`
= `(k + 1)^2/square`
R.H.S. = `(b + c)^2/(b.square) = (square + square)^2/(square*square) = (square (k + 1)^2)/(square*square)`
= `(k + 1)^2/square`
L.H.S. = `square`
