can u help me to find the product of -4x^2 and x^3 + 2x^2 - 5x + 3
and the solution to the equation of x^2 + 30x = 1000...I came up with -20 and 50 but i don't think it is right..can u help
also can you help me to do the factorization of 6x^2 - 2x - 20.....Help please help

For the first problem, just multiply each terms by -4x^2 (e.g., -4x^2 * x^3 = -4x^5). (When multiplying two like terms with exponents, you add the exponents, e.g., -4x^2 * x^3 = -4x * x * x * x *x. )
x^2 + 30x = x(x+30) = 1000 This should help.
What two numbers have a product of -20? Will they give you -2, if 6 times one minus the other gives you -2?
I hope this helps. Thanks for asking.
