how do you factorise y squared - 2y -3?

Factorise xy plus 5yz-2y?
if you take a factor of (Y) you end up with Y(X+5Z-2).
Can you factorise 2x plus 2y?
2(x+y) To find the answer above, look at the question (2x + 2y), and see what the common factors are. In this case, it is "2", which is present in both "x" and "y". Put the "2" on the outside, and write the rest of the equation.
What is the sum of 2y plus 1 and y squared plus 1?
(2y + 1) + (y^2 + 1) = 2y + 1 + y^2 + 1 = y^2 + 2y + 2
What does y plus y equal?
2y
How do you find the solution to x2-4y2 equals 16 and 2y-x equals 2?
x2 - 4y2 = 16∴ (x - 2y)(x + 2y) = 162y - x = 2∴ x = 2y - 2∴ ([2y - 2] - 2y)([2y - 2] + 2y) = 16∴ (y - 1 - y)(y - 1 + y) = 16∴ -1(2y - 1) = 16∴ 1 - 2y = 16∴ -2y = 15∴ y = -7.52y - x = -2∴ -15 - x = -2∴ x = -13So the point of intersection is (-13, -7.5)
2xsquared plus 2y - 8 equals 0 factorise?
2x2 + 2y - 8 = 0 2(x2 + y - 4) = 0 and other than removing the two outside the bracket, this cannot be factorised further, nor simplified.
How do you factor 4x 2y?
(4x)(2y) would be factored as such: 4x = 2 • 2 • x 2y = 2 • y 2(2x)(y)
3x y - 2y?
3xy-2y=0 3xy=2y y=2y (3x) y/2y=3x 1/2=3x multiply across by 2 1=6x 1/6=x therefore substituting x=1/6 into 3xy-2y; 3(1/6)y-2y=0 1/2y=2y y=2y/0.5 0.5 aka 1/2 y=1
What is y times 2?
2y.2y
What is the solution for 3x plus 2y equals -2 and 6x-y equals 6?
(A) 3x + 2y = -2 (B) 6x - y = 6 (A) + 2(B): 3x + 2y + 12x - 2y = -2 + 12 or 15x = 10 or x = 2/3 substitute this value of x in (A) 2 + 2y = -2 2y = -4 and y = -2 Answer: x = 2/3, y = -2
What does y x y eqeal?
Y squared (Y^2)
