4^6x^2 -9x-6=8 -36 -9
______
-12*3| 9
|
(this bit is only from the view of the exponent)
(6x^2-12x)+(3x-6)
6x(x-2)+3(x-2)
(6x+3)(x-2)
3(2x+1)(x-2)
3(x+1/2)(x-2)
x=-1/2 x=2
(checking to see which work)
(2^2(2)-3)(2^3(2)+1)=8^6
(2)(2^7)does not equal 8^6
x is not 2
(2^2(1/2)-3)(2^3(1/2)+1)=8^6
(1/4)(5.7) does not equal 8^6
x is not 1/2
what i want to know is it no solution? or did i make an error along the way?
You can put this solution on YOUR website! solve for x:
(2^2x-3)(2^3x+1)=8^6
-----------
What is the exponent?
Is it (2^2)x - 3 ? Or 2^(2x) - 3 ? Or 2^(2x-3) ?
Use parentheses to clarify.
