Question

Which expression is equivalent to( 9x^2+2x-7)(-4)

Answer 1

Answer:  Option 'b' is correct.

Step-by-step explanation:

Since we have given that

$(9x^2+2x-7)(x-4)$

We need to find the equivalent form:

We will apply "Distributive law":

$a\times b+a\times c\\\\=a\times (b+c)$

So, it becomes,

$x(9x^2+2x-7)-4(9x^2+2x-7)$

Hence, Option 'b' is correct.

Answer 2

Answer:

I'm pretty sure its B. (9x2+2x-7)(x)+(9x2+2x-7)(-4)  

Because its just splitting up the (x-4) and if you add the answers together then you get the same answer as the original
