lcm

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

- 385 x^{4} + 21 x^{3} - 14 x^{2}

Solution steps

Find Least Common Multiplier of

55 x^{2} - 3 x + 2, 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:

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

Simplify

- 385 x^{4} + 21 x^{3} - 14 x^{2}

(- 23), v (- 27), f (- 210)

y, = 3 x + 3

x^{2}, y + 6

55 x^{2} - 3 x + 2582 x^{2} - 9 x^{2}, 5 - 3 x + y + 6

55582 x^{2} - 9 x^{2}, 5 - 3 x + y + 6
