How do you factor y2 plus 8y plus 16?
y2 + 8y + 16 = y2 + 4y + 4y + 16 = y(y + 4) + 4(y + 4) = (y + 4)(y + 4) or (y + 4)2
How do you factor 16y squared - 8y equals 0?
16y^2(8y)=0? Factor out an 8y to give you 8y(2y(2))=0 Use order of operations to give you 8y(4y)=0 Distribute to give you 32y=0 and ultimately the answer will be 0 If there is a missing plus or minus operator between 16y2 and the 8y, then it can be factorised by taking out common factors: 16y2 ± 8y = 0 ⇒ 8y(2y ± 1) = 0
How do you solve 4y x2y?
Times the numbers together, 4 x 2 = 8 Times the independent variables, y x y = y2 answer = 8y2
What is 4y 8y?
4y + 8y = 12y 4y - 8y = -4y 4y x 8y = 32y2 4y/8y = 1/2
What is 2x plus 8y factorised?
2x + 8y --- has a GCF of 2= 2(x + 4y)

Factor 2xy - 4x plus 8y - 16?
( 2xy - 4x ) + ( 8y - 16)2 ( xy - 2x ) + 2 ( 4y - 8 ) Answer
What are the points of contact when the line x equals 2 -2y crosses the curve x2 plus 4y2 equals 4?
Equations: x = 2 -2y and x^2 +4y^2 = 4 If: x = 2 -2y Then: x^2 = 4y^2 -8y +4 If: x^2 +4y^2 = 4 Then: 4y^2 -8y +4 +4y^2 = 4 Collecting and transposing terms: 8y^2 -8y = 0 or y^2 -y = 0 Factorizing the above: (y-1)(y+0) = 0 meaning y = 1 or 0 By substitution points of contact are made at: (0, 1) and (2, 0)
2 - 8 y plus 6 equals 4y-70?
2 - 8y + 6 = 4y - 702 + 6 + 70 = 4y + 8y78 = 12yy = 78/12y = 6.5
What is 4 me 2 plus 4 you 2?
8me+8you because 4y2 = 2(4y) = 8y
What equation is equivalent to 3x - 4y 8?
3x - 4y = 8Solve for x:3x = 4y + 8x = 4/3y + 8/3Solve for y:-4y = -3x + 8y = 3/4x - 2
What is 2x plus 8y use the greatest common factor and the distributive property to write equivalent expression factored form?
Does it look like I fing care Jesus
6x plus 4y equals 32 -6x plus 4y equals 8?
6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2
What equation is equivalent to 3x-4y equals 8?
3x - 4y = 8Solve for x:3x = 4y + 8x = 4/3y + 8/3Solve for y:-4y = -3x + 8y = 3/4x - 2
