5x-13x+6=0 5x-13x=-6 -8x=-6 -8x/-8=-6/-8 x = 3/4
(8x2)-(13x-16)= -78
x + 13x + 10x = 50 - 6
42 + x2 = 13x ∴ x2 - 13x + 42 = 0 ∴ (x - 6)(x - 7) = 0 ∴ x ∈ {6, 7}
6x^2 -13x+6 = (3x-2)(2x-3) when factorized
5x-13x+6=0 5x-13x=-6 -8x=-6 -8x/-8=-6/-8 x = 3/4
(8x2)-(13x-16)= -78
If you mean: 13*(x -1) +6 then it is 13x -13 +6 = 13x -7 as an expression
x + 13x + 10x = 50 - 6
42 + x2 = 13x ∴ x2 - 13x + 42 = 0 ∴ (x - 6)(x - 7) = 0 ∴ x ∈ {6, 7}
6x^2 -13x+6 = (3x-2)(2x-3) when factorized
If you mean: 4x-6+5x = 13x-8 then it works out that x = 1/2 or 0.5
x = -1.
This is a quadratic equation question which will have two answers: 2x2+42 = x2+13x 2x2-x2-13x+42 = 0 x2-13x+42 = 0 Factorising the equation gives you: (x-6)(x-7) = 0 Therefore: x = 6 or x = 7
(8x + 3)(x - 2)
-6 = 3 x -2 13 = 5 x 3 - 2 → 5x² + 13x - 6 = (5x - 2)(x + 3)
You have NOT equated the linear expression. However, equating to zer(0) 13x - 11y - 12 = 0 Then 11y = 13x - 12 y = (13/11)x - 12/11 Hence the slope is '13/11' and the intercept is '-12/11'. However, if you intended to write the expression as an equation 13x - 11y = 12 ( Note the '=/-' signs). Then 11y = 13x - 12 and we have the same equation. y = (13/11)x - 12/11
