The inequality of solution about X: XX − 1 ＜ 1-A

The inequality of solution about X: XX − 1 ＜ 1-A

The original inequality is changed into & nbsp; ax − (a − 1) x − 1 < 0, that is [ax - (A-1)] (x-1) < 0 (3 points) if a ＞ 0, 0 ＜ a − 1a ＜ 1, the solution set of the original inequality is a − 1a ＜ x ＜ 1; if a = 0, 1 x − 1 ＜ 0, the solution set of the original inequality is & nbsp; X ＜ 1; if a ＜ 0, a − 1a ＞ 1, the solution set of the original inequality is x ＜ 1 or X ＞ a − 1a. & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; so (1) if a ＞ 0, the solution set is (a − 1a, 1) (2) if a = 0, the solution set is & nbsp; (- ∞, 1) (3) if a < 0, the solution set is (- ∞, 1) ∪ (a − 1a, + ∞)

0 < α < β, the solution set of inequality ax & sup2; + BX + C > 0 is known as (α, β), and the solution set of inequality (a + C-B) x & sup2; + (b-2a) x + a > 0 is obtained

Equivalence of solution set (α, β) and inequality (x - α) (x - β)

To put it another way, "as time goes on" requires the same meaning, but it's more written,
It's better to write because of time. I use it in my thesis, so the words should be accurate. There's no need for poetry

Over time, over time
"As time goes by"

Solution equation: 81x ^ 2-4 = 0; (X-2) ^ 2 = 4x-8

81x^2-4=0
81x^2=4
x^2=4/81
X = 2 / 9 or x = - 2 / 9
(x-2)^2=4x-8
x^2-4x+4=4x-8
x^2-8x+12=0
(x-6)(x-2)=0
X = 6 or x = 2

There is a rectangular cardboard 8 cm long and 4 cm wide, cut a square from each corner, and then folded into a 1 cm high rectangular paperless carton. What is the volume of the carton?

(8-1 × 2) × (4-1 × 2) × 1 = 6 × 2 × 1 = 12 (cubic centimeter); a: the volume of this carton is 12 cubic centimeter

What are the meanings of all symbols and letters on architectural drawings?

In different regions, according to different local specifications, the meaning of drawing symbols and letters will be different. First of all, you need to see the design basis indicated on the drawings which refer to the specifications

Is the sum of the monomial - m ^ 2n ^ 3x-5 and n ^ 4x-3m ^ 2 the value of X obtained by the monomial

If their sum is still monomial, they can only be of the same kind, so only 3x-5 = 4x-3, x = - 2

What is the relationship between the maximum included angle of a conic generatrix and the degree of its sector in its side view?
Let p be the maximum included angle of a conical generatrix, then the degree of its side expansion sector is 360sin (P / 2)

That's right
sin(P/2) = r / L
Umbrella angle a = 2 π R / 2 π L * 360 = R / L * 360
= 360sin(P/2)

Solution inequality: | x2-3x + 2 | ≤ 0

∵|| x2-3x + 2 | ≤ 0, ∵ x2-3x + 2 = 0, the solution is x = 1, x = 2; the solution set of the original inequality is {x | x = 1, or x = 2}
