Identify common factor: Identify the common factor in both terms.Both terms 6x(3x−10) and 5(3x−10) have a common factor of (3x−10).
Factor out common factor: Factor out the common factor (3x−10). The expression can be written as (3x−10)(6x+5) by factoring out the common factor.
Check factored expression: Check the factored expression by distributing to ensure it matches the original expression.(3x−10)(6x+5)=6x(3x)+6x(−10)+5(3x)+5(−10)=18x2−60x+15x−50=18x2−45x−50Since the original expression is 6x(3x−10)+5(3x−10), and we have an extra term 18x2 which is not in the original expression, we realize there is a mistake.
