Which products result in a perfect square trinomial? select three options. (negative x 9)(negative x minus 9) (x y x)(x y x) (2
erastovalidia [21]

The products that result in a perfect square trinomial is (x + y + x)(x + y + x), (2x - 3)(-3 + 2x) and (4y² + 25)(25 + 4y²)

<h3>What is an polynomial?</h3>

A polynomial is an expression that involves only the operations of a<em>ddition, subtraction, multiplication</em> of variables.

A perfect square trinomial is the square of a binomial

(x + y + x)(x + y + x) = (2x + y)²

(2x - 3)(-3 + 2x) = (2x - 3)²

(4y² + 25)(25 + 4y²) = (4y² + 25)²

The products that result in a perfect square trinomial is (x + y + x)(x + y + x), (2x - 3)(-3 + 2x) and (4y² + 25)(25 + 4y²)

Please help thanks :)

Question 1:

Multiply both sides of the proportion by 35.

You get.

7(x-1) = 4x+2

7x-7 = 4x+2

Now, add both sides by 7 and subtract both sides by 4x

3x = 9

Divide both sides by 3

x=3

Question 2:

Multiply both the numerator and the denominator of \frac{x+1}{x+3} by 3.

We want to multiply it by 3 so that the +1 and +3 become +3 and +9. +3 and +9 have a difference of 6, just like 15 and 21, which is what we want.

\frac{3x+3}{3x+9} = \frac{15}{21}

Set the numerator equal to the numerator and the denominator equal to the denominator.

3x+3 = 15

3x+9 = 21

If you solve both of these, you get x=4 for both.

That's your answer.

Hope this helps! :)
