x3 - 11x2 + 18x = 0
x (x2 - 11x + 18) = 0 . . . . x = 0 is a root.
x (x - 9) ( x - 2) = 0 . . . . x = 9 and x = 2 are roots.
X = 0, 2, 9

9x2-18x plus 9 equals 0 what is the discriminant?
The discriminant is 0.
2X2 plus 18X equals 20?
2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1
What is the x intercept of 18x plus 12y equals 72?
18x + 12y = 72 to get x-int. put y=0 18x + (12)(0) = 72 18x = 72 x = 4 your x-intercept is 4. this is the place where the line goes through the x-axis.
What are the solutions of 2x2 plus 18x-20 equals 0?
Using the quadratic equation formula: x = 1 or x = -10
What is the answer for y equals 3x squared plus 18x plus 15?
Y = 3X^2 + 18X + 15 set to zero 3X^2 + 18X + 15 = 0 divide through by 3 X^2 + 6X + 5 = 0 now easy factor by inspection (X + 1)(X + 5) X = -1 X = -5 -1 checks by inspection and I assume -5 will check also
9x2-18x plus 9 equals 0 what is the discriminant?
The discriminant is 0.
2X2 plus 18X equals 20?
2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1
What is the x intercept of 18x plus 12y equals 72?
18x + 12y = 72 to get x-int. put y=0 18x + (12)(0) = 72 18x = 72 x = 4 your x-intercept is 4. this is the place where the line goes through the x-axis.
What are the solutions of 2x2 plus 18x-20 equals 0?
Using the quadratic equation formula: x = 1 or x = -10
What is the discriminant of the polynomial 9x2-18x plus 9?
It is: 0
What is the answer for y equals 3x squared plus 18x plus 15?
Y = 3X^2 + 18X + 15 set to zero 3X^2 + 18X + 15 = 0 divide through by 3 X^2 + 6X + 5 = 0 now easy factor by inspection (X + 1)(X + 5) X = -1 X = -5 -1 checks by inspection and I assume -5 will check also
What is y equals x2 18x plus 52 in vertex form?
Y = X2 + 18X + 52 set to 0 X2 + 18X + 52 = 0 subtract 52 from each side X2 + 18X = - 52 now, halve the coefficient of the variable term (18), square it and add it to both sides X2 + 18X + 81 = - 52 + 81 now, factor on left and gather terms on right (X + 9)2 = 29 (X + 9)2 - 29 = 0 ---------------------------vertex form
What is x2 equals 18x-80?
x2=18x-80 (im guessing you are trying to find x) x2-18x+80=0 (x-10)(x-8)=0 Therefore: x = 10, 8
What is the simplified sum of 23x plus 189y -5x - 201y?
18x +12y = 0
What is 18x squared minus 9x minus 14 equals 0?
x = -2/3,7/6
What are the solutions to 3 -18x squared equals 25x by factorizing it?
If: 3 -18x^2 = 25x then 3 -18x^2 -25x = 0 When factored: (9x-1)(-2x-3) = 0Solutions: x = 1/9 or x = -3/2
How do you solve 9x squared plus 18x minus 16 equal 0?
9x2 + 18x - 16 = 0 ⇒ (3x - 2)(3x + 8) = 0 ⇒ 3x - 2 = 0 → x = 2/3 or 3x + 8 = 0 → x = -22/3
