lcm x^2-3x+,2x^2-9x^2

lcm

x^{2} - 3 x +, 2 x^{2} - 9 x^{2}

- 7 x^{4} + 21 x^{3}

Solution steps

Find Least Common Multiplier of

x^{2} - 3 x +, 2 x^{2} - 9 x^{2}

Factor

2 x^{2} - 9 x^{2} : (2 + 3) (2 - 3) x^{2}

Multiply each factor with the highest power:

(2 + 3) \cdot (2 - 3) \cdot x^{2} \cdot (x^{2} - 3 x)

Simplify

- 7 x^{4} + 21 x^{3}

4 a + 6 b + 5 c, - 3 a - 9 b, a + 3 b - 4 c

\frac{5}{( x - 7 )}, \frac{3}{( x - 2 )}

x^{2} - 4, x^{3} - 8, x^{2} + 2 x + 4

(13), (\frac{1 a}{3}), (36), (33 b), (48)

x, - 2
