Factor x squared y - xyb - abx plus ab squared?
Factor by grouping. x2y - xyb - abx + ab2 The first two can factor out an xy, so xy(x - b) The second two can factor out a -ab, so -ab(x - b) and we have xy(x - b) - ab(x - b) Since what is inside the parentheses is alike, we can be assured that we have factored correctly and now continue to group: ANS: (x - b)(xy - ab)
What is 4x squared y plus 3x squared y?
4 (apples) plus 3 (apples) = 7 (apples). 4 (cows) + 3 (cows) = 7 (cows) 4 (x2y) + 3 (x2y) = 7 (x2y)
What is the coefficient of the x2y term in the expansion of (x plus 2y)3?
The coefficient is 6.
What is like terms in polynomial?
They are terms in which a variable is raised to the same power (index) in both terms. So x2y and -27x2y are like terms but not xy2.
How do you simplify expression?
Multiply out all brackets (parentheses). Combine "like" terms. "Like" terms are those where any algebraic letters and their powers are exactly the same, but the numbers before them (the coefficients) may be different. Thus 2x2y and 3x2y are like terms and should be combined to make 5x2y. But 2x2y and 3xy2 are not like terms since in the first it is x that is squared while in the second it is y. Similarly, x and x2 are not like terms. Also, when combining terms, remember that x2y is 1x2y.
What is the factor of x2y-xyb-abx plus ab2?
(b - x)(ab - xy)
Factor X squared y plus axy plus abx plus a squared b?
x2y + axy + abx + a2b Factor by grouping. xy(x + a) + ab(x + a) (xy + ab)(x + a)
Factor x squared y - xyb - abx plus ab squared?
Factor by grouping. x2y - xyb - abx + ab2 The first two can factor out an xy, so xy(x - b) The second two can factor out a -ab, so -ab(x - b) and we have xy(x - b) - ab(x - b) Since what is inside the parentheses is alike, we can be assured that we have factored correctly and now continue to group: ANS: (x - b)(xy - ab)
Factor x2y-3x2-2y plus 6?
(x2 - 2)(y - 3)
If I know that x2y plus 4 and I plug that into 3y plus 5x what do I get?
You will get nonsense. You cannot plug x2y + 4 into anything!
How do you factor 3x3-x2y plus 12x-4y?
3x3 - x2y + 12x - 4y = x2*(3x - y) + 4*(3x - y) = (x2 + 4)*(3x - y)
What is -2y plus x2y-8?
It is -2y + x2y - 8, which is an expression that cannot be simplified further, not can it be evaluated.
What is the greatest common factor of x2y and xy2?
xy
What is 4xy plus x3y plus yx2 plus yx plus 3yx simplified?
4xy + x3y + yx2 + yx + 3yx = x3y + x2y + 8xy = (xy)(x2y + x + 8)
What is 4x squared y plus 3x squared y?
4 (apples) plus 3 (apples) = 7 (apples). 4 (cows) + 3 (cows) = 7 (cows) 4 (x2y) + 3 (x2y) = 7 (x2y)
How do you factor x2y-18xy 81y completely?
y(x - 9)(x - 9)
Solve the equation y' plus x2y equals x2?
