How to divide the cubic power of x minus 11x plus 20

How to divide the cubic power of x minus 11x plus 20

=x3-16x+5x+20=x(x2-16)+5(x+4)=x(x+4)*(x-4)+5(x+4)=(x+4)*(x2-4x+5)

Given the quadratic power of X - 3 times of X - 1 = 0, find the value of the cubic power of 2x - 2 times of 3x - 11x + 8
-It's subtraction

Construct x ^ 2-3x = 1
Original formula = 2x (x ^ 2-3x) + 3x ^ 2-11x + 8
=2x+3x^2-11x+8
=3x^2-9x+8
=3(x^2-3x)+8
=3+8
=11

The topic 4x (x-radical 3) + 3 = x square
4X (x-radical 3) + 3 = x square
1.2y-0.04 = 9y square
X square - 5 = 2 radical 3x
Y square + 3y-2 = 0

4X (x-radical 3) + 3 = x square
4X ^ 2-4x radical 3 + 3-x ^ 2 = 0
3x ^ 2-4x radical 3 + 3 = 0
(3x radical 3) (x radical 3) = 0
X = (radical 3) / 3, x = radical 3
1.2y-0.04 = 9y square
9y^2-1.2y+0.04=0
(3y-0.2)^2=0
3y-0.2=0
y=1/15
X square - 5 = 2 radical 3x
X ^ 2-2 radical 3x-5 = 0
(x-radical 3) ^ 2-3-5 = 0
(x-radical 3) ^ 2 = 8
X-radical 3 = radical 8, x = radical 3 + 2, radical 2
X-radical 3 = - radical 8, x = radical 3-2, radical 2
Y square + 3y-2 = 0
(y+3/2)^2-9/4-2=0
(y+3/2)^2=17/4
Y + 3 / 2 = (radical 17) / 2, y = (- 3 + radical 17) / 2
Y + 3 / 2 = - (radical 17) / 2, y = (- 3-radical 17) / 2
