    @keegq ,apply the distributive property. (3)(2x^2-6X-5) - (x)(2x^2-6X-5) now open up the brackets and simplify

    @keegq I meant check the power of x in 2x^2. It is wrong

    @keegq . Yes it should be 6x^2-18x-15-2x^3+6x^2+5x Now add up all the x^2 terms and x terms separately and tell me what you get

    Almost right. Check the sign of 2x^3 term. It should be -2x^3 So your answer should be -2x^3+12x^2-13x-15
