$\\ \rm\longmapsto \dfrac{x-3}{4}=\dfrac{x}{2}$

$\\ \rm\longmapsto 2(x-3)=4x$

$\\ \rm\longmapsto x-3=\dfrac{4x}{2}$

$\\ \rm\longmapsto x-3=2x$

$\\ \rm\longmapsto x-2x=3$

$\\ \rm\longmapsto -x=3$

The polynomial below is a perfect square trinomial of the form A2 - 2AB + B2.

seropon [69]

Answer: Option B.

Step-by-step explanation:

Given the polynomial:

$16x^2-36x+9$

Observe that $16x^2$ and $9$ are perfect squares. Then, you can rewrite the polynomial in this form:

$(4x)^2-36x+(3)^2$

You can identify that:

$A=4\\B=3$

Then, we can check if $2AB=36$

$2(4x)(3)=36x\\\\24x\neq 36x\\\\2AB\neq36x$

Since $2AB\neq36x$ , the polynomial $16x^2-36x+9$ <em>IS NOT </em>a perfect square trinomial of the form $A^2 - 2AB + B^2$

Olenka [21]

6: 1,3,2,6
7: 1,7
Factors of 6 are 1,3,2,6 because 1x6 (6x1) and 3x2. (2x3)

Factors of 7 are 1,7 because seven is a odd number so you can only multiply it by one and itself. (1x7 or 7x1)
