Answer:
24. x = 8.
25. x = -9, 10.
Step-by-step explanation:
The zeros of the functions are the solutions to the equation when y=0. To find the solution, factor each equation.
24. Look for two factors that multiply to 64 and add to -16. The factors are -8 and -8. Write them in binomial forms.
(x-8)(x-8)
So x = 8.
25. Look for two factors that multiply to -90 and add to -1. The factors are 9 and -10. Write them in binomial forms.
(x+9)(x-10)
So x = -9, 10.
