(a)4x^(2)-3x+7

If P = 3x^(3) -5x + 9, Q = 4x^(3) + 5x^(2) -11 and R = 5x^(3) + 4x^(2) -3x +7 , then P -2 Q + R is

Identify polynomials in the following: f(x)=4x^(3)-x^(2)-3x+7g(x)=2x^(3)-3x^(2)+sqrt(x)-1p(x)=(2)/(3)x^(2)-(7)/(4)x+9q(x)=2x^(2)-3x+(4)/(x)+2h(x)=x^(4)-x^((2)/(3))+x-1f(x)=2+(3)/(x)+4x

If alpha and beta are the roots of 4x^(2) + 3x +7 =0 then the value of 1/alpha + 1/beta is

If alpha and beta are the zeros of the polynomials P(x)=4x^(2)+3x+7 thent 1/(alpha)+1/(beta) is equal to …………..

If alpha,beta are the zeros of the polynomial p(x)=4x^(2)+3x+7, then (1)/(alpha)+(1)/(beta) is equal to ( a )(7)/(3)(b)-(7)/(3)(c)(3)/(7)(d)-(3)/(7)

If f(x)=4x^(2)+3x-7 and alpha is a common root of the equation x^(2)-3x+2=0 and x^(2)+2x-3=0 then the value of f(alpha) is
