Question

the zeros of the quadratic polynomial X square + 9 X + 18 are both positive words negative for one positive and one negative and both equal

Answer 1

Answer:

zeroes of quadratic equation x^2+9x+18 are -3 and -6

Explanation:

x^2+9x+18

=x^2+6x+3x+18

=x(x+6)+3(x+6)

=(x+6)(x+3)

=x=-3,x=-6

Therefore both the zeroes of the equation are negative
