How can you simplify x2 plus 2x-35x2 plus 4x-21?
It is: 4x -34x^2 -21 simplified
What is x2 times 2x?
x2 × 2x = 2x3
Simplify 5x2 - 7x - 2x - x2?
Separate and simplify the common terms. 5x^2 - X^2 = 4x^2 -7x - 2x = -9x Now put these terms back together 4x^2 - 9x Or if simplified further, you get: x(4x-9)
How do you factor x2 2x-3?
x2 + 2x - 3 = (x + 3)(x - 1)
What is the factor of equals X2-2x-15?
x2-2x-15 = (x+3)(x-5) when factored
Simplify x2 plus 2x?
x(x + 2)
How do you simplify X2 plus 2x plus 4?
Factor it out: (x+2) squared
How can you simplify x2 plus 2x-35x2 plus 4x-21?
It is: 4x -34x^2 -21 simplified
What is x2 2x-15?
x2+2x-15
What is x2 times 2x?
x2 × 2x = 2x3
What is the derivation of x2?
Derivation of x2 or 2x is 2.
What is the Factor x2 plus 2x 63?
x2+2x-63 = (x-7)(x+9) when factored
How to simplify sin x2 cos x2?
If you mean: sin2(x) cos2(x) then it can be simplified by noting that the square of the sine of x is equal to (1 - cos(2x)) ÷ 2 and the square of the cosine of x is equal to (1 + cos(2x)) ÷ 2. We can then simplify further: sin(x)2cos(x)2 = [(1 - cos(2x)) / 2][(1 + cos(2x)) / 2] = (1 - cos(2x))(1 + cos(2x)) / 2 = (1 - cos2(2x)) / 2 Also note that 1 - cos2(x) = sin2(x), so we can then say: = sin2(2x) / 2
X2 over 3x2 -5x-2 -2x over 3 x plus 1 x 1 over x-2?
x2/(3x2 - 5x - 2) - [2x/ (3x + 1)][1/(x - 2)] = x2/(3x2 - 6x + x - 2) - 2x/(3x + 1)(x - 2) = x2/[3x(x - 2) + (x - 2)] - 2x/(3x + 1)(x - 2) = x2/(3x + 1)(x - 2) - 2x/(3x + 1)(x - 2) = (x2 - 2x)/(3x + 1)(x - 2) = x(x - 2)/(3x + 1)(x - 2) = x/(3x + 1)
Convert x2 plus y2 equals 2x?
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
What is 2x times x to the second power plus 9 simplified?
This depends where the brackets go. If the equation you want to simplify is (2x)(x2) + 9 then we just multiply the parts in the brackets. When you multiply powers you add the power, so this is 2x3+9 If the equation is 2x(x2+9) then we need to multiply each part of the bracket by 2x. This gives 2x3+18x
Simplify 5x2 - 7x - 2x - x2?
Separate and simplify the common terms. 5x^2 - X^2 = 4x^2 -7x - 2x = -9x Now put these terms back together 4x^2 - 9x Or if simplified further, you get: x(4x-9)
