OpenStudy (anonymous):

move everything to one side of the equation

OpenStudy (anonymous):

yeah move everything to oneside and then use the quadratic formula

OpenStudy (candy13106):

ok so it will be 10b^2-27b+18=0

OpenStudy (mathstudent55):

Keep 10b^2 on the left side, and move 27b and -18 to the left and make it equal zero.

OpenStudy (mathstudent55):

Good. Now you need to factor.

OpenStudy (mathstudent55):

You have the form \(ax^2 + bx + c = 0\) Multiply a and c together, and find two factors of ac that add to b. In your case, multiply 10 times 18 and find two factors of that product that add to -27.

OpenStudy (candy13106):

idk im trying to figure it out

OpenStudy (candy13106):
