1) Simplify:[16x²+8x+1]/[1-16x²]
=[(4x+1)(4x+1)[/[[1-4x)(1+4x)]
=(4x+1)/(1-4x)
--------------------
2) Multiply and Simplify: x²-7x+12 x²-6x+8
— ————————— . —————————
x²-6x+8 x²-x-6
=[(x-4)(x-3)]/[(x-3)(x+2)]
=(x-4)/(x+2)
---------------------
3) Divide and simplify:5x-7 ÷ 25x² -49
————————————
5x²+27x+28
That's confusing. Use some parentheses.
