The graph of the quadratic function shown on the left is y = –0.7(x + 3)(x – 4).

The roots, or zeros, of the function are
.

Determine the solutions to the related equation
0 = –0.7(x + 3)(x – 4).

The solutions to the equation are x =
.

Explanation:

We'll use the zero product property. This is the idea where if A*B = 0, then either A = 0 or B = 0.

So if

-0.7(x+3)(x-4) = 0

then either

x+3 = 0 or x-4 = 0

Both of those equations solve to

x = -3 or x = 4

The roots are the locations of the x intercepts, which is where the graph crosses or touches the x axis.

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
