I didn't understand the question well hope the answer will help you plz mark me as brainliest if it helps thank u

Step-by-step explanation:

Given equation 

4x2+3x+5=0

Dividing by 4

44x2+43x+45=0

x2+43x+45=0

We know that 

(a+b)2=a2+2ab+b2

Here a=x

2ab=43x

2b=43

b=83

Adding and subtracting (83)2

x2+43x+45+(83)2−(83)2=0
