y=x হল প্যারাবোলার স্পর্শক y=ax^(2)+c। যদি c=2, তাহলে যোগাযোগের বিন্দু হল \n(a) (3,3)\n(b)...

If y=x^(3)-c and y=x^(2)+ax+b touch each other at the point (1,2) , then (|a|+|b|+|c|)/(|a+b-c|)=?

If y=(ax+b)/(x^(2)+c), prove that (2xy_(1)+y)y_(3)=3(xy_(2)+y_(1))y_(2)

If a, b, c, x, y and z be real numbers and x^(2)+y^(2)+z^(2)=16 ; a^(2)+b^(2)+c^(2)=9 ; ax+by+cz=12 ; the value of ((a^(3)+b^(3)+c^(3))^((1)/(3)))/((x^(3)+y^(3)+z^(3))^((1)/(3))) is

Let a, b, c in R . If f (x) = ax^(2) + bx + c is such that a + b + c = 3 and f(x + y) = f(x) + f(y) + xy, AA x, y in R, " then " sum_(n =1)^(10) f (n) is equal to

If y^(2)=ax^(2)+2bx+c," then "(ax+b)^(3)(d^(2)x)/(dy^(2))=

If b+c = 2x, c+a =2y and a +b =2z then value of a^(3) +b^(3) +c^(3) is

If a, b, c, x, y and z be real numbers and x^(2)+y^(2)+z^(2)=16 , a^(2)+b^(2)+c^(2)=9 and ax+by+cz=12 ; the value of ((a^(3)+b^(3)+c^(3))^((1)/(3)))/((x^(3)+y^(3)+z^(3))^((1)/(3))) is
