Question

for what real values of x is the expression x^2-10x+9 positive​

Answer 1

Answer:

fuck ......................

Answer 2

The real values of x are (−∞,−1) ∪ (1,∞).

Given:

An expression x² - 10x + 9.

To Find:

The real values of x.

Solution:

To find the real values of x we will follow the following steps:

As we know,

x² - 10x + 9 > 0

x² - 9x - x + 9 > 0

x(x-9) + 1(x-9) > 0

(x+1) (x-9) ≥ 0

x < -1 and x >9

x ∈ (−∞,−1) ∪ (1,∞)

Henceforth, The real values of x are (−∞,−1) ∪ (1,∞).
