Answer:
Dont you use the a sq. plus b aq. equal c sq.?
17-4x = 1-4x+12-2x
17-4x = 13-6x | +4x
17 = 13-2x | -13
4 = -2x | :(-2)
-2 = x
The zeroes of this function are x = 2, 4.
We can find this by factoring. Factoring x²-6x+8, we get (x-2)(x-4). Now, since we want to find the zeroes, we have to make y equal to zero, or (x-2)(x-4) = 0. Using the zero-product property, we can conclude that if (x-2)(x-4) is 0, x is 2, 4.
X = 8
because 8 x 2 = 16
16 - 9 = 5
5 x 3 = 15
