Before simplifying, how many terms are there in the expression 2x - 5y + 3 + x?

Heather is writing a quadratic function that represents a parabola that touches but does not cross the x-axis at x = -6. which function could heather be writing? fx) = x2 + 36x + 12 = x2 - 36x - 12 f(x) = -x + 12x + 36 f(x) = -x? - 12x - 36

Find the zeros of each function. f(x) = 6x^2 - 7x - 20
