You need to know whether the given factor is x + 5 or x - 5. Then it is a simple problem in long division.
-3(x + 2)(x + 4)
9x(x2+3x-10) * * * * * 9x3 + 27x2 - 90x = 9x(x2 + 3x - 10) = 9x(x + 5)(x - 2).
Since 3x is a factor of 3x^2, it is automatically the GCF.
3x2 - 3x - 60 = 3(x2 - x - 20) = 3(x2 - 5x + 4x - 20) = 3(x[x - 5] + 4[x - 5]) = 3(x + 4)(x - 5)
If that's +42x + 49, the answer is (3x + 7)(3x + 7) or (3x + 7)2 If that's -42x + 49, the answer is (3x - 7)(3x - 7) or (3x - 7)2
−39x−6
27x/9x = 3x
If you mean: -2(3x-3) = 7x-2 then the value of x works out as 8/13
Your question is ambiguous. (3x)^3 times (3x)^3 = 27x^3 times 27x^3 = 729x^6 or, if you meant 3x^3 times 3x^3 = 9x^6
0
It is 14*(3x + 2y)
9 + 9y = 27x -9 -9 9y = 27x - 9 9y/9 = 27x/9 - 9/9 y = 3x -1
3x multiplied by (12x plus 9) is:3x(12x + 9)= (3x * 12x) + (3x * 9)= 36x2 + 27x
(27x3 - 64) = [(3x)3 - 43] = (3x - 4)[(3x)2 + (3x)(4) + 42] = (3x - 4)(9x2 + 12x + 16)
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.....
-38y - 39x (Is that what you were asking for?)
