You multiply out the paranthees, and it would be:
(x²+x-3x-1)(7x-2)
7x³-2x²-14x²+4x-7x+2
=
7x³-16x²-3x+2
note that the weaker degree control when x is being smaller and smaller
draw:
y=7x³
y=-16x²-3x+2 fir example, and when x is reaching zero, the weaker degree gets more in the function as x is reaching small values, like 0.5 for example, in the high ranges of x, it's 7x³ that controlls.
