How do you solve 2x squared minus five equals zero?
2x2-5 = 0 +5 +5 2x2 = 5 /2 /2 x2 = 5/2 sqrt(x2) = sqrt (5/2) x = sqrt(5/2) Ps: Sqrt means square root
How do you solve the equation by using the zero element?
Not sure what you mean by "zero element". If an expression is equal to zero, and you can factor it, then at least one of the factors must be zero; this is often useful to solve an equation.
Is x equals 0 no solution?
Zero is an acceptable value for a variable. As a general rule, if you solve an equation and get x equals zero, that's just what it is: zero. There is one solution. Example: 10x +1 = 5x +1 5x = 1 - 1 5x = 0 x = 0 There is one solution, zero. If you solve for x and get two solutions, such as 2 and 0, there are two answers. Later on, if you've studied domain and range (the numbers you can use for x so that the equation is still defined, (i.e. not 1/0, or the square root of negative 1), you may find that x = 0 does not always work. You need to check first, to see if zero is in the domain, before you say it's an answer.
Which property would you use to solve the equation f divided by 3 equals zero point two seven for f?
Multiplication:- If: f/3 = 0.27 Then by multiplying both sides by 3: f = 0.81
Negative 5 to the zero power equals?

Can you solve x squared minus six plus five equals zero?
X=1
How do you solve x squared minus ten x plus six equals zero?
It can be solved by using the quadratic equation formula.
How do you solve x squared minus ten x plus sixteen equals zero?
Factor it. (x - 8)(x - 2) x = 2, 8
How do you solve x squared minus 4 equals zero?
So u have the function x2-4=0 Now because 4 is a squared number, its square root is 2 (x+2)(x-2)=0
What is X squared plus 6x minus 55?
Without knowing what "x" is, we cannot say what the answer will be. And without knowing the answer, we cannot solve for "x". Set x at zero, for example. Zero squared is zero, plus 6 time zero which is zero, minus 55. Your answer is then -55. Set x at one, for example. One squared is one, plus 6 times 1 which is six, minus 55. Your answer is then -48. Etc.
How do you solve x squared minus two x plus one equals zero?
x2-2x+1 = 0 (x-1)(x-1) = 0 x = 1 and also x = 1
How do you solve minus 2x squared plus 10x minus 14 equal 0?
It can't be solved because the discriminant of this quadratic equation is less than zero
What is zero minus zero Does it equal orange?
Zero minus zero equals zero.
What is six x squared plus seven x minus five equals zero?
x = 5 / 6squared + 7
How do solve three x squared plus five x minus eight equals zero?
3x^2 + 5x - 8 = 0 + 8 + 8 3x^2 + 5x = 0 8x ^2 = 0
What is 0 squared?
0 squared is 0. Zero times zero equals zero.
What is two minus zero minus zero plus zero?
It Equals 2
