Is that supposed to be $(5x - 11)^2$

yes

sleepyjess · Answer

Okay, we just need to expand the binomial, then use FOIL

anonymous · Answer

i got 25x^2-121

sleepyjess · Answer

You are close, can you show me what you did?

anonymous · Answer

Multiply each term in the first group by each term in the second group using the FOIL method. FOIL stands for First Outer Inner Last, and is a method of multiplying two binomials.  First, multiply the first two terms in each binomial group.  Next, multiply the outer terms in each group, followed by the inner terms.  Finally, multiply the last two terms in each group. its going to equal 25x^2-110x+121
