2b^2 • (b^2 + 7b + 4)

Step-by-step explanation:

Step 1 :

Trying to factor by splitting the middle term; Factor b2+7b+4

The first term is, b2 its coefficient is 1 .

The middle term is, +7b its coefficient is 7 .

The last term, "the constant", is +4

Step-1 : Multiply the coefficient of the first term by the constant 1 x 4 = 4

Step-2 : Find two factors of 4 whose sum equals the coefficient of the middle term, which is 7

= 2b^2 • (b^2 + 7b + 4)

I hope this helps.

its c or d   take a lucky guess my dude
