Question

If x equals to -A is a solution of x square - 3 x + K is equal to zero then find the value of k​​

Answer 1

Step-by-step explanation:

x= -A is a solution ...(given)

The given equation is x^2-3x+K=0

Substituting x= -A is the equation.

(-A)^2-3(-A)+K=0

A^2+3A+K=0

K= -A^2-3A.

THE VALUE OF K IS -A^2-3A.
