Question

Solve the following equation by formula method :
0.1x²+ 0.50x + 0.3= 0​

Answer 1

Step-by-step explanation:

comparing with standard form ax^2+bc+c=0

a=0.1 , b=0.50 , c=0.3

b^2-4ac = (0.50)^2 - 4×0.1×0.3

= 25 - 1.2

=23.8

x= -b+/-√b^2-4ac÷2a

x= -0.50+/-√23.8÷2×0.1

x = -0.50+/-√23.8÷0.2

x= -0.50+√23.8÷0.2 or x= -0.5-√23.8÷0.2
