Solve this problem -x squared -40x- 80 =0
u should learn so u dont ask next time so what u do is find the square root of 250 squared or times itself minus 80 squared
actually,10x squared minus 17 equals 63 would come out to x equals the square root of 8.to work this out, you would first at 17 to both sides to get 10x squared alone.63 plus 17 equals 80. you now have 10x squared equals 80. then divide each side by ten to get x squared alone. 80 divided by 10 equals 8. now you have x squared equals eight. finally, to find x, you find the square root of each side. x squared's square root is x, and 8's square root is 2.82842712 but I'm assuming you only have to write out x=√8.but the other answer was a good try:)Improved Answer:-10x2-17x = 6310x2-17x-63 = 0When factored: (5x+9)(2x-7) = 0Therefore the roots of the quadratic equation are: x = -9/5 and x = 7/2
80 minus 4 is 76.
80 minus 12.6 is 67.4
500 - 5x = 100 500 = 100 + 5x 400 = 5x x = 80 Check it. -400 + 500 = 100 It checks.
-80
802 = 80 x 80 = 6400
5x = 80
80 - 45 = 35
-80 - 1 = -81
