What is 2x cubed plus x squared minus 13x plus 6 divided by x minus 2 giving reasons why your answer is correct?
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.

How do you factorise x squared minus x 7?
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.

What is the derivative of 1 divided by x?
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

What is the quotient and remainder of 6x cubed plus 29x squared minus 40x minus 42 divided by 6x plus 5 giving reasons why your answer is correct?
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.
What is x cubed plus 3x squared minus 22x minus 90 divided by x minus 5 giving a reason why your answer is 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.
What is the area of a square with a perimeter of 24 cm?
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.
What is the value of n in the expression 2 x cubed plus nx squared -x -4 which when divided by x -2 leaves 6 remaining and giving a reason why your answer is correct?
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
