Question 1 :
Determine whether the equation $\displaystyle 5{ x }^{ 2 }=5x$ is quadratic or not.
Question 4 :
The sum of roots of the equation$a{x^2} + bx + c = 0$ is equal to the sum of squares of their reciprocals.The$b{c^2},c{a^2}$ and $a{b^2}$ are in
Question 5 :
The mentioned equation is in which form?<br/>$(y\, -\, 2)\, (y\, +\, 2)\, =\, 0$
Question 6 :
If $a(p+q)^{2}+2 b p q+c=0$ and $a(p+r)^{2}+2 b p r+c=0$ <br> $(a \neq 0),$ then,
Question 7 :
If $x_1$ and $x_2$ are the roots of $3x^2 - 2x - 6 = 0$, then $x_1^2 + x_2^2$ is equal to
Question 8 :
If in applying the quardratic formula to a quadratic equation<br>$f(x) = ax^2 + bx + c = 0$, it happens that $c = b^2/4a$, then the graph of $y = f(x)$ will certainly:
Question 9 :
Each of the equations $3x^2 - 2 = 25, (2x - 1)^2 = (x - 1)^2, \sqrt{x^2 - 7} = \sqrt{x - 1}$ has
Question 10 :
The sum of the squares of the two consecutive positive integers exceed their product by $91.$ Find the integers?
Question 12 :
if A=(0), B =(X:X>15 and x<5), c=(x:x-5=0), D=(x:${ x }^{ 2 }$=25) E=(x :xis a positive integer root of equation ${ x }^{ 2 }$-2x-15 =0, then pair of equal sets is:<br/>
Question 14 :
Assertion: If $\displaystyle a+b+c=0$ and $a, b, c $ are rational, then roots of the equation $\displaystyle \left (b+c-a \right )x^{2}+\left (c+a-b \right )x+\left ( a+b-c \right )=0 $ are rational.
Reason: For quadratic equation given in Assertion, Discriminant is perfect square.
