What are the values of x in 2x2 -3 equals -6x -2?
2x2-3 = -6x-2 2x2+6x-3+2 = 0 2x2+6x-1 = 0 When factored with the help of the quadratic equation formula: (2x-0.3166247904)(x+3.1583123952) = 0 Therefore: x = 0.1583123952 and also x = -3.1583123952
What is 2x2 equals 6x?
2x2 = 6x2x2 - 6x = 02x (x-3) = 0Now set each part being multiplied equal to zero separately: 2x=0 and x-3 = 0. That means x = 0, 3.
6x plus 2 equals 6 how do I get the answer?
6x + 2 = 6 6x = 4 x = 2/3
What is the absolute value of 3 - 6x which equals 15?
3-6x = 15 -6x = 15-3 -6x = 12 x = -2
What does 9x plus 3-6x-2 equals to?
9x + 3 - 6x - 2 = 3x + 1
What are the values of x in 2x2 -3 equals -6x -2?
2x2-3 = -6x-2 2x2+6x-3+2 = 0 2x2+6x-1 = 0 When factored with the help of the quadratic equation formula: (2x-0.3166247904)(x+3.1583123952) = 0 Therefore: x = 0.1583123952 and also x = -3.1583123952
X2 plus 6x-2 equals -2x2 plus x?
x2 plus 6x-2 equal -2x2 plus x ..=7x equal -3x2 ..4x=2x=2 answer ..check it if u dont want to trust ..Improved Answer:x2+6x-2 = -2x2+xx2+2x2+6x-x-2 = 03x2+5x-2 = 0(3x-1)(x+2) = 0x = 1/3 or x = -2The answer can be checked by using the quadratic equation formula.
What is 2x2 equals 6x?
2x2 = 6x2x2 - 6x = 02x (x-3) = 0Now set each part being multiplied equal to zero separately: 2x=0 and x-3 = 0. That means x = 0, 3.
Factor 2x squared plus 6x - 8 equals 72?
2x2 + 6x - 8 = 72 ∴ 2x2 + 6x + 64 =0 ∴ x2 + 3x + 32 = 0 This can not be factored, as x is not equal to any integer. Using the quadratic equation, we find that: x = -3/2 ± √119 / 2i
What is the answer for 6x equals 2 over 3?
If: 6x = 2/3 Then: x = 1/9
6x plus 2 equals 6 how do I get the answer?
6x + 2 = 6 6x = 4 x = 2/3
What is the absolute value of 3 - 6x which equals 15?
3-6x = 15 -6x = 15-3 -6x = 12 x = -2
What does 9x plus 3-6x-2 equals to?
9x + 3 - 6x - 2 = 3x + 1
Manuel says that the graph of 3y-36 equals 2x2-18x is an ellipse with its major axis parallel to the y-axis Shanice disagrees Who is correct?
3y - 37 = 2x2 - 18x3y = 2x2 - 18x + 37y = (2/3)x2 - 6x + (37/3)The graph is a parabola.Shanice outshines Manuel.
What is the value of x if 2x squared -5x equals 3?
2x2 - 5x = 3 ∴ 2x2 - 5x - 3 = 0 ∴ 2x2 + x - 6x - 3 = 0 ∴ x(2x + 1) - 3(2x + 1) = 0 ∴ (x - 3)(2x + 1) = 0 ∴ x ∈ {-0.5, 3 }
What is equivalent to y equals x2 - 6x plus 14?
The following equations are all equivalent to y = x2 - 6x + 14:y - 5 = (x - 3)22y = 2x2 - 12x + 28± √(y - 5) = x - 3y = [x4 - 4(3x3 + [4x]2 - 42x + 49)]1/2y - 5 = x2 - 6x + 92y - 5 = 2(x2 - 6x) + 23x = 3 ± √(y - 5)
6x to the power of 2 -4x to the power of 2 plus 3?
6x2-4x2+3 = 0 2x2 + 3 = 0 2x2 = -3 x2 = -3 / 2 this equation has imaginary roots x = +sqaureroot (3/2)i , -sqaureroot (3/2)i where i = complex variable
