If the sum of the roots of the equation `kx^2+2x+3k=0` is equal to their product then the value of k
`(a) 1/3 (b)-1/3 (c)2/3 (d)-2/3`
उत्तर
Given:
`kx^2+2x+3k=0`
Sum of the roots = Product of the roots
⇒ `-2/k=(3k)/k`
⇒ `3k=-2`
⇒` k=(-2)/3`

In the adjoining fig. `square` ABCD is a trapezium AB || CD and its area is 33 cm2. From the information given in the figure find the lengths of all sides of the `square` ABCD. Fill in the empty boxes to get the solution.
Solution: `square` ABCD is a trapezium.
AB || CD
`"A"(square "ABCD") = 1/2 ("AB" + "CD") xx`______
33 = `1/2 ("x" + 2"x" + 1) xx `______
∴ ______ = (3x + 1) × ______
∴ 3x2 +______ − ______ = 0
∴ 3x(______) + 10(______) = 0
∴ (3x + 10) (______) = 0
∴ (3x + 10) = 0 or ______ = 0
∴ x = `-10/3` or x = ______
But length is never negative.
∴ `"x" ≠ -10/3`
∴ x = ______
AB = ______, CD = ______, AD = BC = ______
