How can i solve for this would it best to factor or use the quadratic formula. solve: x^2+2x-8=0 How about for this problem as well: solve : x^2+7x-1 = 0 in the first, can you think of two multipliers of -8 that have a sum of 2?? how about 4 and -2 so it factors! in the secon...

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 terms ...

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 the quadratic (x+10)(x+6)

I need help can someone help me get unstuck and let me know if i am correct.thank you. solve by completing the square. 4x^2+2x-3=0 this is what i am doing: i used the quadratic equation. so where i am is in this step: x = (-2 (+-) sqrt (-44))/(8) from this point i am stuck: Pr...

My qustion is for the following the problem reads as follows (x-1)^2 = 7 x-1=+- sqrt 7 x= 1+- sqrt 7 the method they use was factoring in order to simplify the equation to make it easier is this correc? x^2-9x-4=6 x^2-9x-10=0 (x-10)(x+1)=0 What method did they use here I think...
math , question
Can someone give me an example of how might anyone apply radical expressions and their applications to the daily life of themselves. Well square root of 25 is 5 now A^2 + B^2 = C^2 We need to see if a box is square. So we measure down one side 3' the the other 4'. Now ...
