x^2-6x>= 7

Solution

x^{2} - 6 x \geq 7

Solution

x \leq - 1 or x \geq 7

+1

Interval Notation

(- \infty, - 1] \cup [7, \infty)

Solution steps

x^{2} - 6 x \geq 7

Rewrite in standard form

x^{2} - 6 x - 7 \geq 0

Factor

x^{2} - 6 x - 7 : (x + 1) (x - 7)

(x + 1) (x - 7) \geq 0

Identify the intervals

x \leq - 1 or x \geq 7

6(x+3)-4=5(2-x)

6 (x + 3) - 4 = 5 (2 - x)

(2x+1)/x-x/(x+2)<= (x^2+2x+4)/(x^2+2x)

\frac{2 x + 1}{x} - \frac{x}{x + 2} \leq \frac{x ^{2} + 2 x + 4}{x ^{2} + 2 x}
