It cannot be solved because the discriminant of the quadratic equation is less than zero


No because the discriminant of the given quadratic expression is less than zero.


How do you solve 4y plus x equals 8


This quadratic equation which will have two solutions can be solved by completing the square or by using the quadratic equation formula.Completing the square:x2+18x+4 = 0(x+9)2+4 = 0(x+9)2+4-81 = 0(x+9)2 = 77x+9 = + or - the square root of 77x = -9 + or - the square root of 77If you're not too sure about the procedure of completing the square your maths tutor should be familiar with it.


X2+11x+11 = 7x+9 X2+11x-7x+11-9 = 0 x2+4x+2 = 0 Solve as a quadratic equation by using the quadratic equation formula or by completing the square: x = -2 + or - the square root of 2


Not enough information to solve


2x2+12x+1 = 0 By dividing all terms in the quadratic equation by 2 will make completing the square easier to work out: x2+6x+0.5 = 0 (x+3)2+0.5 = 0 (x+3)2-9+0.5 = 0 (x+3)2-8.5 = 0 (x+3)2 = 8.5 x+3 = the square root of 8.5 x = -3 and plus or minus the square root of 8.5


x2 + 20x +0 =30 [(20/2)2 =100] x2 + 20x + 100 =30 +100 √(x+10)2=√130 x+10=√130 x= −10+√130 √ means square root


This question cannot be answered. You will have to give me the number to the square root. * * * * * a = ±sqrt(c^2 - b^2)


x2 - 16x + 68 = 5 (x - 8)2 + 4 = 5 (x - 8)2 = 1 x - 8 = 1 or -1 x = 9 or 7



x = the square root of -1, an imaginary number written as a lower case italic i.


Y equals 1 and X equals 1


Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7



you can not solve this equation


The equation does not have a solution.


25x (square) plus 40 plus 15 equals 680.



9y subtract 11 equals 7


To solve for x, we'd have to know what this expression equals.


You can't solve it. But you can simplify it to get: 4x+y=2


If: x^2 +18x = 29 Then completing the square: (x+9)^2 -81 = 29 or (x+9)^2 = 110


i have no clue what the answer is
