3x3+15x2+18x = 3x(x2+5x+6) = 3x(x+2)(x+3)
18x + 45 or 9(2x + 5) how is this answer figured?
18x is a monomial because it only has a single x.
81. To complete the square, halve the coefficient of the x term (18/2 = 9) and add the square of this (92 = 81) to both sides: x2 + 18x = -13 ⇒ x2 + 18x + 81 = -13 + 81 ⇒ (x + 9)2 = 68
It is equal to -18x^2 +9x
Divide all terms by 2 and it can then be factored to (2x+1)(5x+2)
First divide by 6: 6(x2 - 3x + 2) = 6(x - 1)(x - 2)
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
Do you mean: factorise: 27x2-18x-18 best I can get is: 9((3x-2)-2)
First step should be to take everything to the left side:6x2 - 18x - 12 = 0Next you might divide by the common factor, 6:x2 - 3x - 2 = 0It seems you have to use the quadratic formula for this one. Use a = 1, b = -3, c = -2.First step should be to take everything to the left side:6x2 - 18x - 12 = 0Next you might divide by the common factor, 6:x2 - 3x - 2 = 0It seems you have to use the quadratic formula for this one.

if this is the Equation 9X^2 - 18X +9 = Zero 9(X^2 - 2X +1)= Zero divide both side on 9 the result will be X^2 - 2X = -1 X(X - 2) = -1 and so X= -1 ............. or X-2 = -1 and so X = 1 the result is the value of x are between {-1,1}.
6x2-18x+12 = (6x-6)(x-2)
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
(x+9)^2 =x^2 + 9 X^2 + 18x + 81 = X^2 +9 18X + 72 = 0 18X = -72 X =- 4
If that's + 18x + 1, the answer is (9x + 1)(9x + 1) or (9x + 1)2
(2x4) + (8x3) + 18x 8 + 24 + 18x 32 + 18x
18(2 - x)
