4x-x^2>3

Solution

4 x - x^{2} > 3

1 < x < 3

Interval Notation

(1, 3)

Solution steps

4 x - x^{2} > 3

Rewrite in standard form

4 x - x^{2} - 3 > 0

Factor

4 x - x^{2} - 3 : - (x - 1) (x - 3)

- (x - 1) (x - 3) > 0

Multiply both sides by

- 1

(reverse the inequality)

(- (x - 1) (x - 3)) (- 1) < 0 \cdot (- 1)

Simplify

(x - 1) (x - 3) < 0

Identify the intervals

1 < x < 3

- 16 = x + (- 6)

9 x^{0} y - 3

\frac{2}{3} x - 12 = 180

20 + 4 x < - 4

2 x - 5 \geq - 241
