Solution

3 (x^{2} - 2 x - 6)

Solution steps

3 (x - 1)^{2} - 21

Factor out common term

3 : 3 ((x - 1)^{2} - 7)

= 3 ((x - 1)^{2} - 7)

\frac{2 π}{\frac{7}{3}}

simplify (4a^{-2}b^{-3})/(3a^2b^1)simplify

\frac{4 a ^{- 2} b ^{- 3}}{3 a ^{2} b ^{1}}

x^{2} + 10 x = 30

-3m-3(8m+3)=6(6m+9)

- 3 m - 3 (8 m + 3) = 6 (6 m + 9)

(x-4)/(x^2+16)<0

\frac{x - 4}{x ^{2} + 16} < 0
