Answer: 4x+25=0 is an unfactorizable quadratic equation and so one formula is there to solve it....
Step-by-step explanation: Here, we know the general form of a quadratic equation is ax+by+c=0. In the above equation, a=4, b=0 and c=25. So the formula is---
x= -b +or-√b^2-4ac÷2a
= +or-√0-4×4×25÷2×4
= +or-√-400÷8
= EITHER x= -√400 ÷8 or x=√400÷8=20/8=5/4
