Answer:
a = 4
Step-by-step explanation:
Here, we want to write and solve the given equation
a - 2.5 = 1.5
a = 2.5 + 1.5
a = 4
To check, we simply substitute a = 4
That would be;
4-2.5 = 1.5
This is correct
There are no values for x that make the equation true
(x^2 +5x+2.5^2) +4+5
(x+2.5)^2+9
vertex -2.5,9
