I didnt post the problem right, thanks for posting though. I'll have to make another post.Have you considered multiplication?
As suggested earlier, the first step will be to multiply out and simplify the given expression. Then you'll want to "equate coefficients". That is, you'll find the term in the first expression that has "s" in its coefficient, and you'll look at the corresponding term in the given simplified form. Since the polynomials can be equal only if their coefficients are the same, then you can equate the two relevant coefficients, and solve for the value of "s".A polynomial expression is shown below:
. . . . .(12x^{5} - 30x^{4}) - (sx^{3} - 7)(2x^{2} - 5x + 3)
The expression is simplified to:
. . . . .-18x^{3} + 14x^{2} - 35x + 21
What is the value of s?
Can you show me step-by-step how you would do that? btw the problem is a picture attachment.As suggested earlier, the first step will be to multiply out and simplify the given expression.

You already have loads of step-by-step worked solutions in your book and in your class notes, so us doing this exercise for you isn't likely to make much difference. Now is the time to try something!Can you show me step-by-step how you would do that? btw the problem is a picture attachment.
