If f(1) = 0, what are all the roots of the function f (x) = x cubed 3 x squared minus x minus 3? Use the Remainder Theorem. X =
LiRa [457]

All the roots of the provided function If f(1) is equal to the zero are -3, -1 and 1.

<h3>What is polynomial?</h3>

Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).

The function given in the problem is,

f(x)=x^3+3x^2-x-3

If f(1) = 0

f(1)=(1)^3+3(1)^2-(1)-3\\f(1)=1+3-1-3\\f(1)=0

Thus, (x-1) is one of the factor of polynomial. Equate the polynomial equal to the zero, to find other roots as,'

x^3+3x^2-x-3=0\\x^2(x+3)-1(x+3)=0\\(x+3)(x^2-1)\\(x+3)(x+1)(x-1)=0

Equate all the groups to zero to find the roots as,

x+3=0, x=-3\\x+1=0, x=-1\\x-1=0, x=1

Hence, all the roots of the provided function If f(1) is equal to the zero are -3, -1 and 1.

ALLL MY POINTS PLSSS HELPPPPP
Rama09 [41]

Rewrite the given quadratic equation in standard form: Kx 2 + 2x - 1 = 0  

Discriminant = 4 - 4(K)(-1) = 4 + 4K  

For the equation to have two real solutions, the discriminant has to be positive. Hence we need to solve the inequality 4 + 4K > 0.  

The solution set to the above inequality is given by: K > -1 for which the given equation has two real solutions.
