Question : Which of the following equations has equal roots?
Option 1: $3x^{2}-6x+2=0$
Option 2: $3x^{2}-6x+3=0$
Option 3: $x^{2}-8x+8=0$
Option 4: $4x^{2}-8x+2=0$
Correct Answer: $3x^{2}-6x+3=0$
Solution : An equation has equal roots if its discriminant is zero. The discriminant of a quadratic equation $ax^{2}+bx+c=0$ is given by $b^{2}-4ac$. Option (i): $3x^{2}-6x+2=0$ So, $D=(-6)^{2}-4×3×2=36-24$ $\therefore D=12$ > 0 Option (ii): $3x^{2}-6x+3=0$ So, $D=(-6)^{2}-4×3×3=36-36$ $\therefore D=0$ Option (iii): $x^{2}-8x+8=0$ So, $D=(-8)^{2}-4×1×8=64-32$ $\therefore D=32$ >

Question : In $\Delta ABC$ the straight line parallel to the side $BC$ meets $AB$ and $AC$ at the point $P$ and $Q,$ respectively. If $AP=QC$, the length of $AB$ is $\operatorname{12 units}$ and the length of $AQ$ is $\operatorname{2 units}$, then the length (in units) of $CQ$ is:
Option 1: $4$
Option 2: $6$
Option 3: $8$
Option 4: $10$
Correct Answer: $4$
Solution :
Given that $AP=QC$, $AB=\operatorname{12 units}$ and $AQ=\operatorname{2 units}$ Let $AP=QC=x\operatorname{ units}$ Since $PQ$ is parallel to $BC$, then, $\Delta ABC\sim\Delta APQ$ Since the triangles are similar, the ratios of their corresponding sides are equal. $\frac{AP}{AB}=\frac{AQ}{AC}$ ⇒ $\frac{x}{12}=\frac{2}{2+x}$ ⇒ $2x+x^2=24$ ⇒ $x^2+2x-24=0$ ⇒ $(x+6)(x-4)=0$ ⇒ $x=4$
