Answer by RAY100(1637) (Show Source): You can put this solution on YOUR website!
we believe the numerator of second multiplier should be (21) not (2)
Please confirm
.
{ (x^2 +x-2) / (x^2 -7x) } * { (5x^2 -38x +21) / (x^2 +2x) }
.
factor
.
{ (x-1)(x+2)/ (x)(x-7)} * { (5x-3)(x-7) / x(x+2) }
.
simply by canceling opposing like terms
.
{ (x-1)(5x-3) } / x^2
.
check by allowing x=1,,both original and answer are zero
try allowing x=2,, both are 1.75,,,,ok
