Simplify the first expression.
(ab)2 = (ab)(ab) = a · a · b · b = a2b2
Substitute some numbers for a and b to confirm the algebraic manipulations you used are correct.
The first expression is equivalent to the second expression.
See part (b).
Substitute some numbers for a and b to confirm the algebraic manipulations you used are correct.
The first equation is equivalent to the second equation.
Are these expressions equal for every value x?
This is an example of a place to investigate how using 0 gives a different result than other numbers.
The expressions are equivalent except when x = 0.
Rewrite the first equation in y-form.
Substitute some numbers for a and b to confirm the algebraic manipulations you used are correct.
The first equation is equivalent to the second expression.
Remember, (a + b)2 means to square the quantity a + b. You can use a generic rectangle to help you.
Substitute some numbers for a and b to confirm the algebraic manipulations you used are correct. Remember to be careful about using only 0 and 1. They can work and not work in very specific cases, often worth mentioning.
The first expression is NOT equivalent to the second expression.
