Sidana [21]3 years ago

Answer:

a)  (x/2 +3)^2

b)  (5a -3b)^2

c)  (x/3 +y/5)^2

d)  (10b -3c)^2

e)  (a/4 -2b)^2

Step-by-step explanation:

Assuming you can do that, write the terms of the quadratic in lexicographical order. (The square terms will be first and last.) Then the binomial is the "sum" of the square roots of the first and last terms with the sign of the middle term.

Using (e) as an example, the term are already in order. (In (d), they need to be rearranged.) The first term is 1/16a^2, and its square root is 1/4a = a/4. The last term is 4b^2 and its square root is 2b. The sign of the middle term is negative, so these two roots will be separated by a minus sign:

  (a/4 - 2b)^2

The expression you want is the square of the binomial.

_____

As a check, you can make sure that double the product of these terms is the middle term of the trinomial you started with.

In this example, that double product is 2·a/4·(-2b) = -ab, which exactly matches the middle term you started with.

The area of a rectangle is length*width.

The length of this 3x and the width is 2x-3. This means that, to find the area, you need to multiply 3x and 2x-3.

Start by writing out this equation:
A=l*w

Then, plug in your given values:
A= 3x*2x-3 (you can also write it as A= 3*x*2*x-3)

Then, following the order of operations, you start by multiplying. This makes your equation become A = 6x^2 -3. (^2 means squared). It turns into this because 3 * 2 is 6 and x * x is x^2 and you still haven’t used the 3 yet.

After this, there is nothing more that you can do to simplify the equation. Therefore, the area is 6x^2 - 3.

I hope this helped!
