Which binomials are a difference of squares?

kow [346]

Answer:

Options B and C.

Step-by-step explanation:

Difference of squares is defined as

$a^2-b^2$

where, a and b both area real numbers.

$y^4+9\Rightarrow (y^2)^2+3^2$

It is sum of squares.

$9x^2-16\Rightarrow (3x)^2-4^2$

It is difference of squares.

$m^6-25\Rightarrow (m^3)^2-5^2$

It is difference of squares.

$m^7-1\Rightarrow m^7-1^2$

It is not a difference of squares.

Therefore, the correct options are B and C.

(x+3)(x+1)=(x+6)(x)
x^2+x+3x+3=x^2+6x

3=2x
x=1.5
