Answer:
The required equation is
.
Step-by-step explanation:
If a quadratic equation is
, then the quadratic formula is

The given quadratic equation is

Here, a=1, b=-9 and c=-20.
Substitute a=1, b=-9 and c=-20 in the above quadratic formula.

Therefore the required equation is
.
Do 7x4= 28 then add z
7x8= 56 then add b
so your answer is 28z + 56b
