This is an expression therefore there is no equal sign. ( "=" )
(2z-5) + (8z^2 - z +7)
2z-5+8z^2-z+7
z+2+8z^2
use the associative property. combine like terms. reduce the expression.

It would need to have an equal sign for it to be an equation...
It can, however, be simplified:
2z - 5 + 8zË2 - z + 7
8zË2 + z + 2
Hope I helped!

Combine like terms? It's not an equation, there is no "="
8z^2+z+7
If you meant that it was equal to 0... then it has no real solution, but if you use the Quad. Form.
[-1+-sqrt(1-224)]/16 which would be
-1/16 +- i*sqrt(223)

I assume there is another half to this to make it an equation. Just combine terms until you form a quadratic equation so the "=0" is on the other size and then solve for the roots.

(2z-5) + (8zsquared - z +7)
(2z-5) + (8z^2 - z +7)
2z-5+8z^2 - z +7
8z^2 +2z- z +7-5
8z^2 +z +2
8z^2 +z +2
a=8, b=1,c=2
the formula is
[-b+-sqrt(b^2-4ac)]/[2a]
now substitute the values
[-1+-sqrt({1}^2-{4*8*2})]/[2*8]
[-1+-sqrt(1-{64})]/[16]
[-1+-sqrt(-63)]/[16]
[-1+-7.94i]/[16]
[-1+7.94i]/[16] or [-1-7.94i]/[16]

Well, this is not an equation since you don't have it set to anything, so I would leave it alone.
You can combine like terms, making it 8z^2+z+2, but there is nothing else to do since it is not an equation rather an expression.
