Help! How do I factor this?
Given: \(5x^3-15x^2-140x\)Factor out a 5x: \(5x(x^2-3x-28)\)Find two numbers that multiply to -28 and add up to -3. In this case, -7 and 4: \(5x(x-7)(x+4)\)
given <<5x^3-15x^2-140x>>factor out everything in common5x(x^2-3x-28)factor polynomial within the parentheses 5x(x+4)(x-7)
