How do you solve 20x2 plus 27x plus 9 equals 0?
20x^2 + 27x + 9 = 0 20x^2 + 15x +12x + 9 = 0 5x(4x + 3) + 3(4x + 3) = 0 (5x + 3)(4x + 3) = 0 So either (5x + 3) = 0 which yields x = -3/5 or (4x + 3) = 0 which yields x = -3/4
Vertex of 9x2-27x plus 20?
x=13.5
What does x equal in 14(3x plus 4) plus x-5(14x-8)?
Impossible to say, because you have not equated the mathematical expression with any number. Assuming it is zero(0) Then 14(3x + 4) + x - 5(14x - 8) = 0 Multiply out the brackets 42x + 56 + x - 70x + 40 = 0 27x + 90 = 0 27x = -90 x = -90/27 x = -30 / 9 x = - 10 / 3 = -3 1/3 = -3.333.....
2275.91 equals x plus 27x?
2275.91 = 28xx = 81.2825
What are the zeros or x-interecepts or soultions or roots of the quadratic equation -7x2 - 27x plus 28 equals 0?
Using the quadratic equation formula:- x = -4.706950048 and x = 0.849071913
3x2 plus 27x equals 30?
3x2 + 27x = 30 ∴ x2 + 9x - 10 = 0 ∴ (x + 10)(x - 1) = 0 ∴ x ∈ {-10, 1}
How do you factor 2x2-27x plus 36?
(2x - 3)(x - 12)
How do you factor 4x plus 27x plus 18?
4x + 27x + 18 = 0 31x + 18= 0 31x + 18 - 18= 0 - 18 31x = -18 31x / 31 = -18 / 31 x = -.58
How do you solve 20x2 plus 27x plus 9 equals 0?

How do you factor 9x squared plus 27x minus 36?
9x2 + 27x - 36 = 9(x2 + 3x - 4) = 9(x + 4)(x - 1)
How do you solve x plus 3 plus 6x plus 9 equals 0?
If: x+3+6x+9 = 0 then 7x+12 = 0 So: 7x = -12 and x = -12/7
How do you solve x squared plus 12x?
Factor. X^2 + 12X X(X + 12) = 0 X = 0 ------------- X + 12 = 0 X = - 12 --------------
