Identify Common Factors: Look for common factors in pairs of terms.We will first look at the terms 3x3 and −6x2 to see if there is a common factor. We can factor out 3x2 from both terms.3x3−6x2=3x2(x−2)
Factor Out Common Factors: Look for common factors in the remaining pair of terms.Now we will look at the terms −10x and +20 to see if there is a common factor. We can factor out −10 from both terms.−10x+20=−10(x−2)
Combine Factored Pairs: Combine the factored pairs.We have factored the polynomial into two pairs: 3x2(x−2) and −10(x−2). We notice that both pairs have a common binomial factor of (x−2).So, we can factor (x−2) out of the entire expression.3x3−6x2−10x+20=(x−2)(3x2−10)
Check Quadratic Factor: Check if the quadratic factor can be factored further.We now have the expression (x−2)(3x2−10). We need to check if the quadratic 3x2−10 can be factored further. Since 3x2−10 does not have any common factors and it does not fit the form of a difference of squares or any other easily factorable form, it cannot be factored further.
