Derivation of x2 or 2x is 2.
What do you want to convert it to? x2 + y2 = 2x If you want to solve for y: x2 + y2 = 2x ∴ y2 = 2x - x2 ∴ y = (2x - x2)1/2 If you want to solve for x: x2 + y2 = 2x ∴ x2 - 2x = -y2 ∴ x2 - 2x + 1 = 1 - y2 ∴ (x - 1)2 = 1 - y2 ∴ x - 1 = ±(1 - y2)1/2 ∴ x = 1 ± (1 - y2)1/2
2x = x2 + 4x - 3 x2 + 2x - 3 = 0 (x - 1)(x - 2) = 0
x3 - x2 + 2x = x*(x2 - x + 2) which cannot be factored further.
x2 + 2x - 15 = (x - 3)(x + 5)
x2+2x-15
x2 × 2x = 2x3
x2 - 15 = 2x x2 - 2x - 15 = 0 x2 - 2x - 15 = (x - 5)(x + 3) x = 5, -3
Derivation of x2 or 2x is 2.
x2+2x-63 = (x-7)(x+9) when factored
What do you want to convert it to? x2 + y2 = 2x If you want to solve for y: x2 + y2 = 2x ∴ y2 = 2x - x2 ∴ y = (2x - x2)1/2 If you want to solve for x: x2 + y2 = 2x ∴ x2 - 2x = -y2 ∴ x2 - 2x + 1 = 1 - y2 ∴ (x - 1)2 = 1 - y2 ∴ x - 1 = ±(1 - y2)1/2 ∴ x = 1 ± (1 - y2)1/2
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).
Add numbers with the same signs: Number, Variable, and Variable Squared or another power.Actually, since X is the same variable, cross both 2x and x2 out of the problem, then add 5 and 3.x2 - 2x - 5 + 3= x2 - 2x - 2= (x2 - 2x + 1) -1 - 2= (x - 1)2 - (√3)2= (x - 1 - √3) (x - 1 + √3) you can rewrite it (if you want)= [x - (1 + √3)][x - (1 - √3)]
2x = x2 + 4x - 3 x2 + 2x - 3 = 0 (x - 1)(x - 2) = 0
The antiderivative of 2x is x2.
x3 - x2 - 2x +2 you can divide this into two parts for now x3 - x2 and -2x +2 factor out everything you can from both x2(x-1) and -2(x+1) since the insides of the parentheses are the same, we can put them together, then multiply it by the sum of the two parts outside the parentheses. (x-1)(x2-2)
x2 + 2x - 3 = (x + 3)(x - 1)
