How do you solve 11x equals 20x Plus 18?
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
Factor x to the fourth power plus 2x to the third power minus 9x to the second power plus 18x?
x4 + 2x3 - 9x2 + 18x = x(x3 + 2x2 - 9x + 18) which I do not think can be factorised further.
20x plus 7 equals 5x plus 10?
20x+7=5x+10 15x=3 3/15=.2 x=.2
X2 plus 20x plus 4 equals 0?
x2 + 20x + 4 = 0 x2 + 20x + 100 = 96 (x + 10)2 = 96 x + 10 = ±961/2 x = -10 ±961/2 x = -10 ±4√6
How do you get 81-18x plus xsquared from (9-x)squared?
Because: (9-x)(9-x) = 81-18x+x^2
How do you solve 11x equals 20x Plus 18?
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
20x -2 18x -4?
x=-1
X2 plus 36 equals 20x?
x2 + 36 = 20x so x2 - 20x + 36 = 0 so x2 - 2x - 18x + 36 = 0 or x(x - 2) - 18(x - 2) = 0 that is (x - 2)(x - 18) = 0 so x - 2 = 0 or x - 18 = 0 ie x = 2 or x = 18
Factor 4x2 plus 20x plus 25?
4x2+20x+25 (2x+5)^2
How do you simplify x plus 2 plus x-22x plus 1?
Combine all lie term: x + x - 22x = -20x 2 + 1 = 3 So the answer is -20x +3 or 3 - 20x
Factor x to the fourth power plus 2x to the third power minus 9x to the second power plus 18x?
x4 + 2x3 - 9x2 + 18x = x(x3 + 2x2 - 9x + 18) which I do not think can be factorised further.
20x plus 7 equals 5x plus 10?
20x+7=5x+10 15x=3 3/15=.2 x=.2
Factor the trinomial 6x2-18x plus 12?
6x2-18x+12 = (6x-6)(x-2)
What is 5x(x plus 4)?
5x^2 + 20x
How do you factor 2x2 plus 18x plus 36?
2(x + 6)(x + 3)
X2 plus 20x plus 4 equals 0?
x2 + 20x + 4 = 0 x2 + 20x + 100 = 96 (x + 10)2 = 96 x + 10 = ±961/2 x = -10 ±961/2 x = -10 ±4√6
Factor 3x cubed plus 15x squared plus 18x?
3x3+15x2+18x = 3x(x2+5x+6) = 3x(x+2)(x+3)
