B i think don’t come at me if it’s wrong lol
Answer:
It will have 3 roots
The number of roots in an equation equals the highest power of that equation.
Step-by-step explanation:
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,
If 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,'

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

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

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.
