What pattern is represented by the polynomial ?

Ymorist [56]

Answer:

choice C. Perfect square trinomial is correct.

Step-by-step explanation:

We need to find the pattern which is represented by the polynomial $4x^2+12x+9$ .

To find that pattern, we need to factor $4x^2+12x+9$

$4x^2+12x+9$

$=4x^2+6x+6x+9$

$=2x(2x+3)+3(2x+3)$

$=(2x+3)(2x+3)$

$=(2x+3)^2$

which is a perfect square.

Hence choice C. Perfect square trinomial is correct.

Which number can each term of the equation be multiplied by to eliminate the fractions before solving?

scoray [572]

Answer: 12

Step-by-step explanation:

You can multiply by 12 because to get rid of the fractions all terms should be divided by the LCM (ie the smallest multiple that is exactly divisible by 2, 4 and 3)

Multiples of 3 = 3, 6, 9, 12

Multiples of 4 = 4, 8, 12, 16

Multiples of 2 = 2, 4, 6, 8, 10, 12

Therefore the fractions should be multiplied by 12
