User: How do you Factor: 2x^2 + 7x + 3.

User: How do you Factor 8y^2 + 17y + 2?

Weegy: I would factor and all that stuff, but I like using the -b+or- the square root of b^2-4ac all over 2a So, [ do b^2-4ac first: 17^2-4(8)(2) 289-64=225 Now find the square root of 225= 15 Now do -17+ 15 - - - - - - 2(8) -2/(2X8) -2/16= -0.125 Now do -17-15 - - - - - 2(8) -32/16= -2 Plug in these two numbers for y and if the equation equals 0 then that's your answer for x. ]
