Question

Factorize. 4a²+12a+9.​

Answer 1

Answer:

No two such Factors can be found

Step-by-step explanation:

Factoring  4a2+12a-9

The first term is,  4a2  its coefficient is  4 .

The middle term is,  +12a  its coefficient is  12 .

The last term, "the constant", is  -9

Step-1 : Multiply the coefficient of the first term by the constant   4 • -9 = -36

Step-2 : Find two factors of  -36  whose sum equals the coefficient of the middle term, which is   12 .

     -36    +    1    =    -35

     -18    +    2    =    -16

     -12    +    3    =    -9

     -9    +    4    =    -5

     -6    +    6    =    0

     -4    +    9    =    5

     -3    +    12    =    9

     -2    +    18    =    16

     -1    +    36    =    35

Observation : No two such factors can be found !!
