Hey!!
What is a standard form in a quadratic equation?
... y = ax² + bx + c
In this equation, x and y are points where as a,b and c are the constants.
We have:
... y = (x+4)(x-6)
... y = (x)(x)+(x)(-6)+(4)(x)+(4)(-6)
... y = x² - 6x + 4x - 24
Combining the like terms.
... y = x² - 2x - 24 Is the standard form.
Hope my answer helps!
