Quadratic equation x2-7x equals 60?
x2 - 7x = 60 x2 - 7x - 60 = 0 (x - 12) (x + 5) = 0 x = 12 or x = -5
X2 - 3x - 10 equals?
If you factor x2 - 3x - 10, you'll get (x-5) (x+2). If your equation is x2 - 3x -10 = 0, then x = 5, and x = -2.
What is the factor of equals X2-2x-15?
x2-2x-15 = (x+3)(x-5) when factored
X2 plus 7x plus 10 equals?
The value of x2+7x+10 depends on the value of X. If x=1, then x2+7x+10 = 18 If x=2, then x2+7x+10 = 28 If x=3, then x2+7x+10 = 40 and so forth
How would you work this problom If y equals 25 when X equals 5 what is the value of y when x equals 20?
There is no one solution to this problem. For example: y = x2 y = 5x y = x + 20 y = 2x / 5 + 23 These are just four of the infinite set functions that would give "y" a value of 25 when x = 5.
X2 equals 5 find the value x?
x=5/2 or 2.5
If y equals -2 when x equals 4 find x when y equals 5?
x1:y1 = x2:y2 4:-2 = x2:5 x2 = (4*5)/-2 x2 = -10
When x equals 5 and y equals 2 find the value of x2 plus 2y?
x2 + 2y = 52 + 2*2 = 25 + 4 = 29
When x equals 8 what is the value of x2?
If x = 8 then x2 = 82 = 8 x 8 = 64
What is the value of the function x2 plus 3 at x equals 5?
f(x) = x2 + 3 ----> f(5) = (5)2 + 3 ----> f(5) = 28
X2 plus x-30 equals 0?
x2 + x - 30 = (x + 6)(x - 5)
All that apply to x2 equals 25?
x = +5 or x = -5
X2 plus 5 equals 30?
x = +5 or -5
What is x2 plus 2x-15 equals?
x2 + 2x - 15 = (x - 3)(x + 5)
What is the solution to x2-4x-5 equals 0?
x = -1 or x = 5
What does x2-5x equals 0?
x2 - 5x = 0x (x - 5) = 0x = 0andx = 5
What is x2 plus x2 mean?
If you have an equation of x2 plus x2, it is the same as saying 2 times x plus 2 times x. This can be written as 2x + 2x or x2 + x2. It is the same, then, as 4x. For example, if x equals 5: 2(5) + 2(5) = 10 + 10 = 20. 20 also equals 4(5).
