Answer 1

Can you share your works/steps, please?

Answer 2

i have this example, just not sure with the fractions and everything

Answer 3

i think it would either be a or c

Answer 4

This one does not relate to ours!

Answer 5

then im not really sure

Answer 6

@3mar

Answer 7

Can you multiply by \(-2\) to make the coefficient of \(x^2\) equal to \(1\)??

Answer 8

yes so
2/4 and 18/4

Answer 9

Can you please multiply by 2 again to eliminate the (1/2) at x?

Answer 10

i dont get what you are saying

Answer 11

Can you please multiply by 2 again to not have any fraction in the equation?

Answer 12

so 1x^2 ?
sorry i am just confused

Answer 13

@3mar

Answer 14

\[\Huge \frac{ -1 }{ 2 }x^2-\frac{ 7 }{ 4 }x-\frac{ 9 }{ 2 }=0\]
multiply by -4 to eliminate all fractions:
\[\huge -4*\frac{ -1 }{ 2 }*x^2+4*\frac{ 7 }{ 4 }x+4*\frac{ 9 }{ 2 }=0\]

then
\[\huge 2x^2+7x+18=0\]

so \(a=2~~b=7~~c=18\)

Can you now use the quadratic formula to solve such equation?
