    x = (-5 +/-ã85)/10 do you mean -0.5 or -5 is this right? solve by using the quadratic formula: 5x^2+5x=3 i get: x= -0.5 (+/-)((sqrt(85)/(5)) check up on your proper use of the formula I got x = (-5 +/-√85)/10 which, if you want to separate it into two

    is this correct? solve: 9x^2=14 this is what i did: i divide 9 by both sides x^2=1.6 is this first step right Then take the square root of both sides. x^2=1.6 you said to take the squar root of both sides. so is this correct x = 1.264911

    Is this right: Solve: x^2+16x+60=0 this is what i did: i used the quadratic formula and this is what i ended up with. x = -8 +- (sqrt(16))/(2) Which is -8 +-2 Or you could have factored the quadratic (x+10)(x+6) Which is -8 +-2 Or you could have factored
