Ageneral formula for a parabola is y2 = 4px. what is the value of p in the equation y2 = –4x?

p= -1

Explanation:

We have been given parabola along positive side of x-axis with equation

after equating the values of  we will get

4px =-4x

Divide each term by x on both left hand side and right hand side  we will get

4p= -4

Now, divide each term by 4 on both left hand side and right hand side we will get the final result p=-1

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
