f(x)=(x-1)(x+2)(x-2) over all it equals to zero
Answer:
(x-1) (x-2) (x+2)
Step-by-step explanation:
1. Factorice x^2 y -4 de la expresion.
x^2(x-1) -4(x-1)
2. Luego, debemos de factorizar x-1 de la expresion.
(x-1)(x^2 -4)
3. Usando a^2 - b^2= (a-b)(a+b) factorice la expresion.
Answer: 6 units
10 x 3^2
= 10 x 9
= 90
22.5
find the scale factor
13.5/9 = 1.5
or
18/12 = 1.5
Then times 15 by this to get x
15 x 1.5 = 22.5
