Trying to factor by splitting the middle term

3.1     Factoring  9v2-9v-1  

The first term is,  9v2  its coefficient is  9 .

The middle term is,  -9v  its coefficient is  -9 .

The last term, "the constant", is  -1  

Step-1 : Multiply the coefficient of the first term by the constant   9 • -1 = -9  

Step-2 : Find two factors of  -9  whose sum equals the coefficient of the middle term, which is   -9 .

     -9    +    1    =    -8  

     -3    +    3    =    0  

     -1    +    9    =    8  

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
