Use synthetic substitution to evaluate the polynomial for the given value x = -3. p(x) = 2x2 + 7x - 1

I'm assuming that is 2x squared, and not 2 multiplied by 2, as a given question usually wouldn't come in such a silly format. I do wish people would start using (2x^2) or (2x²), though.

Just substitute the value of x (-3) in to the equation to find the value of y, or P(x).

2(-3)² + 7(-3) - 1 = -4

The equation is y=17(7)+600 and it equals 717
