3X2 - 3X 3X(X - 1) -----------------------factored, so 3X is gfc
9x2 + 12x + 4 = 9x2 + 6x + 6x + 4 = 3x(3x + 2) + 2(3x + 2) = (3x + 2)(3x + 2) = (3x + 2)2
The expression can be factored as -12x + 32y -16z = 4(-3x + 8y - 4z) but a slightly improved presentation would be to extract -4 from the original expression. So, -12x + 32y -16z = -4(3x - 8y + 4z)
3x
2(3x^2 + 6x + 2)
3x multiplied by (12x plus 9) is:3x(12x + 9)= (3x * 12x) + (3x * 9)= 36x2 + 27x
3x * (x - 4) = 3x*x - 3x*4 = 3x^2 - 12x.
If this is algebra then; 3x plus 12x = 15x
3X2 - 3X 3X(X - 1) -----------------------factored, so 3X is gfc
3x+12x = 15 15x = 15 x = 1
12x + 131 = 189 + 3x 12x - 3x + 131 - 189 = 0 9x - 58 = 0 9x = 58 x = 6,44444
The value of X in the equation 3x 2-12x plus 9 is 1.25.
9x2 + 12x + 4 = 9x2 + 6x + 6x + 4 = 3x(3x + 2) + 2(3x + 2) = (3x + 2)(3x + 2) = (3x + 2)2
3x * (x - 4) = 3x*x - 3x*4 = 3x^2 - 12x.
3x3+12x = 3x(x2+4)
3x+10=12x-17
3x/(5-x)/3=4 3x/(5-x)=4X3 3x=12(5-x) 3x=60-12x 3x+12x=60 x=4
