Hello, alostgirl!
Who is assigning these problems? . . . This one is silly!
We have: \(\displaystyle \:40x^2\,+\,95x\,+\,30\:=\:0\)
Divide by 5: \(\displaystyle \:8x^2\,+\,19x\,+\,6\:=\:0\)
Factor: \(\displaystyle \
x\,+\,2)(8x\,+\,3)\:=\:0\)
Hence: \(\displaystyle \:x\,=\,-\frac{3}{8},\:-2\)
Answers: \(\displaystyle \,-0.3750,\;-2.0000\)
