You have to use Pythagorean theorem
12^2+20^2 = x^2
sqrt(144*400) = x^2
sqrt(544) = x
X = 4 sqrt(34)
The answer is (1,-4)
Remember that the vertex is the center of the parabola.
no they are different
if Base are equal power are added
like wise in first expressions power are added
but in second expressions cube of three is written as x to the power.
so they are not equal
