Question

What is the LMC for 2x^2 - 8x + 8 and 3x^2 + 27x -30?

Answer 1

2

Explanation:

1st step: solve the exponential number

2x^2=4x

3x^2=9x

2nd step: rewrite the number sentence with the exponent solved

4x-8x+8 9x+27x-30

3rd step : solve

4x-8x=-4x 9x+27x=36x

-4x+8= 36x-30=

4 6

Step 4: See what least common multiples they have in common

4 LCM =2 * 2= 4 6 LCM= 2*3=6

So the LCM is 2
