    Any ideas? Hint: a difference of squares can be factored into the sum of two numbers times their difference.

    Hey! Ok first we write 36 as a square in order to express x2-36 as a difference squares so what do we get?

    I barley started learning this, since a square is 4 is it 36/4? Im just taking a guess?

    v^2 — 36 = v^2 — 6^2

    Well it was like this 6^2 before right? so they put it into this 36 b.c 6^2=36 so now they want it back to 6^2 @ninowletonzalez06

    so if we put it back to 6^2 we get \[v ^{2}-6^{2}\]

    since the symbol is subtraction it should be D since both of the signs are (-)

    Ok lets try this :D Lets use difference of squares which the formula is \[a ^{2}-b ^{2}=(a+b)(a-b)\]

    Determine if the expression is a perfect square and if it is, factor it. a2 – 8a – 16 A. (4a + 1)2 B. (a + 4)(a – 4) C. (a – 4)(a – 4) D. not a perfect square
