What is 9y squared plus 66y plus 121?
9y2+66y+121 = (3y+11)(3y+11) when factored
What is a factor of x3 plus 27y3?
x3+27y3 = (x+3y) · (x2-3xy+9y2)
What is y plus 3 to the third power plus 2 divided by 4?
It depends on where there are parentheses, if there are any. y + 33 + 2/4 = y + 27.5 (y+3)3 + 2/4 = y3 + 9y2 + 27y + 27.5
What is 9y2 X Y2?
If Y = y, then it is 9y4 or 9Y4. If Y is not the same as y, then you can't simplify it any.
What is the center of this hyperbola -4x2 plus 9y2 plus 16x-18y plus 29 equals 0?
-4x2 + 9y2 + 16x - 18y +29 = 0 (I hope this is what you meant) 9y2 - 18y - (4x2 -16x) +29 = 0 (group together the x's and y's, and make the x2 term positive. 9(y2 - 2y) - 4(x2 - 4x) +29 = 0 (remove common factors) 9(y - 1)2 - 1 - 4(x - 2)2 - 4 + 29 = 0 (complete the squares) 9(y - 1)2 - 4(x - 2)2 = -25 (move constants to right-hand side) [(y - 1)2] - 4[(x - 2)2]/9 = -25/9 (divide by coefficient in front of x or y bracket, in this case 9) [(y - 1)2]/4 - [(x - 2)2]/9 = -25/36 (divide by coefficient in front of other bracket, in this case 4) As you can see, we now have our equation in standard form. Our center points satisfy [(x - 2 = 0) , (y - 1 = 0)], thus our center is (2,1).
Factor 9x2 - 18xy 9y2?
We are missing an important sign (+/-) I shall assume 9x2 - 18xy + 9y2 9(x-y)(x-y)
What is 9y squared plus 66y plus 121?
9y2+66y+121 = (3y+11)(3y+11) when factored
What is a factor of x3 plus 27y3?
x3+27y3 = (x+3y) · (x2-3xy+9y2)
How do you factor 16x2 plus 8x plus 1- 9y2?
16x2 + 8x + 1 - 9y2 = (4x + 1)2 - (3y)2 which is a difference of two squares. = (4x + 1 + 3y)*(4x + 1 - 3y)
Factor a perfect square?
To factor a perfect square, it should be in the form a2+2ab+b2 For example: 9x2+18xy+9y2 First factor out the 9: 9(x2+2xy+y2) Make a2+2ab+b2 into (a+b)2 : 9(x+y)2
What is the standard equation for the hyperbola 4x2-9y2-8x plus 54y equals 113?
4x2-8x-9y2+54x=113(4x2-8x ) + (-9y2+54y ) =1134(x2-2x+1) -9(y2-6y+9) =113+4-81 because of distribution4(x-1)2 - 9(y-3)2 = 36Divide by 36(x-1)2 - (y-3)2 =19 4
How do you factorize 27y3 plus 125z3?
27y3 + 125z3 = (3y + 5z)*(9y2 - 15yz + 25z2).
How do you factorise -9y-6 6xy 4x?
6xy+9y2
What is y plus 3 to the third power plus 2 divided by 4?
It depends on where there are parentheses, if there are any. y + 33 + 2/4 = y + 27.5 (y+3)3 + 2/4 = y3 + 9y2 + 27y + 27.5
How do you factor completely x3 27y3?
(x + 3y)(x2 - 3xy + 9y2)
How do you factor 9y2 24xy 16x2?
(4x + 3y)(4x + 3y) or (4x + 3y)2
How do you factor 12x2-27y2?
3(2x + 3y)(2x - 3y)
