+1

Interval Notation

(- \infty, 3] \cup [5, \infty)

Solution steps

x^{2} - 8 x + 15 \geq 0

Factor

x^{2} - 8 x + 15 : (x - 3) (x - 5)

(x - 3) (x - 5) \geq 0

6(2x-3)=9x+12+3x

6 (2 x - 3) = 9 x + 12 + 3 x

simplify 4/n ((16i)/n-(16i^2)/(n^2))simplify

\frac{4}{n} (\frac{16 i}{n} - \frac{16 i ^{2}}{n ^{2}})

x^{2} + 8 x + 11 = 0

x^{2} - 3 x - 33 = 0
