Provided that x- 2 is not zero:
2x3 + x2 - 13x + 6 = 2x3 - 4x2 + 5x2 - 10x - 3x + 6
= 2x2*(x - 2) + 5x*(x - 2) - 3*(x - 2)
= (x - 2)*(2x2 + 5x - 3)
Therefore,
(2x3 + x2 - 13x + 6)/(x - 2) = (x - 2)*(2x2 + 5x - 3)/(x - 2) = 2x2 + 5x - 3
If x = 2 so that x - 2 = 0, then the expression is not defined.
The answer to this depends on what you mean by "x 7" If you mean: x2 -7x, then it can be factored out as x(x - 7) If you mean: x2 - x7, then you can factor it out as: x2(1 - x5) If you mean: x2 - x + 7, then it can not be factored If you mean: (x2 - x)7, then the inner term can be factored, giving you (x[x - 1])7 If you mean something else, then you will need to be more clear with your question.

Find dy/dx of y=1/x. It may be simpler for you to examine the equation y=x^-1. This equation is the exact same as y=1/x. Therefore just multiply -1 by x and subtract 1 from the exponent giving you -x^-2 or y=-(1/x^2). You can also do it through quotient rules. Therefore take the derivative of the top 1 which = 0 and multiply that by the bottom X which will give you 0. Then subtract the derivative of the bottom x this equals 1 and multiply it by the top (1). Put this all over the bottom squared. Which leads to -1/x^2. y=1/x = y=x^-1 = -x^-2 = -(1/x^2)=dy/dx or y=1/x = ((0*x)-(1*1)/x^2 = dy/dx=-1/x^2

6x3+29x2-40x-42 divided by 6x+5 is x2+4x-10 remainder 8 or as x2+4x-10+8/(6x+5) If the answer is correct then the quotient multiplied by the divisor should be the same as the dividend:- (6x+5)*(x2+4x-10) + (6x+5)*8/(6x+5) Multiply term by term with (6x+5):- 6x3+5x2+24x2+20x-60x-50+8 Collect like terms:- 6x3+29x2-40x-42 which makes the answer correct.
x3+3x2-22x-90 divided by x-5 equals x2+8x+18 For the answer to be correct then the quotient multiplied by the divisor must be equal to the dividend. Hence:- (x-5)*(x2+8x+18) Multiplying out the brackets term by term: x3-5x2+8x2-40x+18x-90 Collecting like terms in descending order: x3+3x2-22x-90 So the answer is correct.
24 / 4 = 66 x 6 = 36cm2Perimeter is divided by the number of sides of the square.The length of one side (6cm) is squared, giving the area in square centimetres.
Since it's x2*x2, you would add the exponents giving you x4
2x3+nx2-x-4 Using the remainder theorem: n = -1 So the expression is now: 2x3-x2-x-4 When divided by x-2 = 2x2+3x+5 remainder 6 or 6 over x-2 The answer is correct because: (x-2)*(2x2+3x+5+6/x-2) = 2x3-x2-x-4
Could be a variety of reasons: It may not be in the correct category. this makes it hard for the knowledgeable people in the topic to find the question. It may not be a complete question, or provide enough information to be answered.

XIX is the correct roman numeral for 19.Another Answer:-Nowadays it is XIX but in ancient Rome it was IXX because its Latin word is undeviginti meaning one from twenty and there is no Latin word for the equivalent of XIX
7 to the power of 5 squared would be written (75)2 Working the brackets first, you would take 7 to the power of 5, which is 7x7x7x7x7, giving 16,807 16,807 is then squared, and 16,807x16,807 = 282,475,249 so that would be your answer.
