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...

I am stuck form this point i need help. the problem states: A ball is thrown upward from the roof of a building 100 m tall with an initial velocity of 20 m/s. Use this information for exercises 35 to 38. Science and medicine. When will the ball reach a height of 80 m? h=-5t^2+...

Okay i am still trying to understand how to come up with a radical expressions and their applications, and apply to your daily life. I need more examples if any can help me out .... Is there a way of modeling it if i wanted to use a house for instance i just don't know how...

i AM REPLYING BACK TO EVERYONE AND TO THE QUESTION OF ANOTHER FELLOW STUDENT ABOUT THIS WEBSITE. THE FOLLOWING: Let me just say WOW.To everyone and all us students are extra lucky to actually have help from each and everyone of you than not knowing what to do with assingments ...

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 ...
