SOLUTION: A quadratic equation is written in 4 equivalent forms below. y = x2 - 14x + 48 y = (x - 6)(x - 8) y = (x - 7)2 - 1 y = x(x

SOLUTION: A quadratic equation is written in 4 equivalent forms below. y = x2 - 14x + 48 y = (x - 6)(x - 8) y = (x - 7)2 - 1 y = x(x - 14) + 48

Question 745704: A quadratic equation is written in 4 equivalent forms below.
y = x2 - 14x + 48
y = (x - 6)(x - 8)
y = (x - 7)2 - 1
y = x(x - 14) + 48

The first two are the same, yes. The third one, can't be sure unless we try to complete the square. The last one, yes it's same as the first two. It just shows that you have a constant added to an expression for a rectangle. Back at x^2-14, you would add (14/2)^2 in order to Complete The Square. That's 49. Begin with the , try using the Complete The Square process and see what the final standard form equation looks like. Note, you have to both ADD 49 and SUBTRACT 49 to keep the equation the same.

....... and there it is!
