x3 + 13x2 + 42x = x(x2 + 13x + 42) = x(x2 + 6x + 7x + 42) = x[x(x + 6) + 7(x + 6)] = x(x + 7)(x + 6)

4x2-42x+110 = (2x-10)(2x-11) when factored

5x - 42x + 5 = - 37 x +5

42x+35x-35x=42x it's leave 85 so it's change into a negative 42x-85 is the answer

The GCF is 14.

It is 14*(3x + 2y)

It is: 42x+30x^2

(7x + 6)(49x^2 - 42x + 36)

-1/19=x

Collect the like terms;42x-23 = 940Add 23 to both sides;42x = 963Divide both sides by 42;x = 963/42

3(x - 8)(x - 6)

-18x2-42x=-6x(3x+7)

42x + 1 = 8x - 1Subtract 1 from each side:42x = 8x - 2Subtract 8x from each side:34x = -2Divide each side by 34:x = -2/34 = -1/17

-8 + 7x = x - 506x = -42x = -6

(-7x + 3)(-7x +3)

x+5/7 = 11/6 Multiply all terms by 42: 42x+30 = 77 42x = 77-30 42x = 47 Divide both sides by 42: x = 47/42

if x-42x-8=0 x=-5.12500

y-42x = 24 >> Add 42x to both sides << y=24+42x >> Subtract 24 from both sides << y-24=42x >> Divine both sides by 42 << x=(y-24)/42

You said that 42x - 3 + 7 = 8x + 5 .Combine the like terms on the left side (the -3 and the +7):42x + 4 = 8x + 5Subtract 4 from each side:42x = 8x + 1Subtract 8x from each side:34x = 1Divide each side by 34:x = 1/34The solution set is: {34}

x2 - 42x + 441 = (x - 21)2

If you mean: -2(3x-3) = 7x-2 then the value of x works out as 8/13

2x + 4 = 362x = 36 - 42x = 32x = 32/2X = 16

12x - 8 = 10x + 42x = 12x = 6
