Question

State the restrictions:12x2+31x + 93x2-5x-2

Answer 1

we have the expression

`(12x^2+31x+9)/(3x^2-5x-2)`

Remember that

the denominator can not be equal to zero

so

Find the roots of denominator

using a graphing tool

`3x^2-5x-2=0`

the roots are

x=-1/3 and x=2

that means

`3x^2-5x-2=3(x+(1)/(3))(x-2)`

the restrictions are x=-1/3 and x=2
