Consider 8x2 - 48x = - 104. Write the equation so that a = 1

In order to re-write the quadratic equation s/t a=1, we proceed as follows; The general quadratic formula is:

y=a (x-h) ^2+k where (h, k) is the vertex;

hence;

8x^2-48x=-104

dividing through by 8 we get:

x^2-6x=-13 ... i

Using completing square method;

c = (b/2) ^2

c = (-6/2) ^2=9

adding 9 on both sides of equation i we get:

x^2-6x+9=-13+9

(x-3) ^2=-4

this can be written as:

y = (x-3) ^2+4

where:

a=1

h=3

k=4
