F(x)= (x-1)(x(x+1)+2x) find all rational zeros​

Mathematics
1 answer:
pantera1 [17]3 years ago
5 0

Answer:

x = 0, x = 1, x = - 3

Step-by-step explanation:

To find the zeros, let f(x) = 0 , that is

(x - 1)(x(x + 1) + 2x) = 0  ← distribute and simplify parenthesis

(x - 1)(x² + x + 2x) = 0

(x - 1)(x² + 3x) = 0 ← factor out x from the second parenthesis

x(x - 1)(x + 3) = 0

Equate each factor to zero and solve for x

x = 0

x - 1 = 0 ⇒ x = 1

x + 3 = 0 ⇒ x = - 3

Tresset [83]

Answer:

Follows are the solution to this question:

Step-by-step explanation:

The principal characteristics of algebra, a significant degree of complexity, and the logical scientific evidence or universality of application could be considered as an argument. It often operates in maths without any equivalent concepts and methods throughout the real world. In some cases, computational processes and approaches are applied in different fields without a great understanding of the essence of the process. Another argument is the use of formal logic as well as the accuracy of evidence extracting.

E.x 20/8

10/4=20/8 then cross multiply

10×8=80 and 20×4=80

80=80

Another one is 45/18.

10/4=45/18

10×18=180 45×4=180
