Question

2. The trinomial p(x) = x3-x has three real zeroes.
3. 5 x = 2 (4-1) is not a linear equation in two variables.​

Answer 1

Answer:

sorry but I don't know about this

Answer 2

Answer:

2. The three real zeros are 0, -1 and 1.

3. yes, it's not a linear equation with two variables. because there is only 1 variable which is x.

Step-by-step explanation:

x³ - x = 0

x(x² - 1) = 0

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

∵ x = 0, x - 1= 0

and x + 1 = 0

x = 0, x = 1 and x = -1

5x = 2(4x - 1)

5x = 8x - 2

8x - 5x - 2 = 0

5x - 2 =0
