Transcribed Image Text:20. Find all the roots of f(x)=3x³ +18x² - 48x (you can find them by factoring)
f(x) = 3x†18x²- 48x
82 3x(x18)(x-2) =
X= 0,-8,2
3x(x+ 6x-16)

21. Factor the following completely. x³ – 3x² – 4x + 12
x*(x-3)- 4 (x-3)
(x-3)(x-u)
|= (x-3)(x-2)(x*2)|
22. Solve the following for all solutions, both real and imaginary. f(x) = 2x² – 17x +30 x – 8. Since it can't
be factored then use guess and check with synthetic division.

24. Solve by Factoring: 2x2- 15 = -x
2x-15t X =0
2x + X-15=O
25. Solve using any method: -3x² – 30x - 27 = 0.
2x+ lox-5x-15
2x (x*+ 3x)- 5(X13) =0
