Answer 1

Answer:

thanks for asking❤

Step-by-step explanation:

Given that 1 is the zero of quadratic polynomial x^2 + kx - 5, it means that the value of x is 1 and on applying the value of x( i.e. 1 ) result of the given polynomial will be 0. Substitute the value of x in the quadratic polynomial. Therefore the value of k satisfying the given quadratic polynomial is
