Answer:

Yes , the products of both expressions are the same

Step-by-step explanation:

Given

(-5 + x)( x + 4)

Using the distributive property we have

-5xx -5x4 + xxx +xx4

Negative times positive becomes negative

-5x - 20 + x^2 + 4x

Also (5 + x)(x - 4)

Using the distributive property

5xx +5-4 + xxx +xx-4

5x^2 -20 + x^2 - 4x

The product of -5 + x and x + 4 is equal to the product of 5 + x and x - 4

If x2 mx m is a perfect-square trinomial, which equation must be true? x2 mx m = (x – 1)2 x2 mx m = (x 1)2 x2 mx m = (x 2)2 x2 m

Leno4ka [110]

An expression has numbers, variables, and mathematical operations. The equation that must be true so that x²+mx+m is a perfect square trinomial is x²+mx+m=(x+2)².

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

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

A perfect square trinomial is in the form (a+b)²=a²+b²+2ab. If we compare the perfect square trinomial x²+mx+m, we will get that the value of m should be such that it satisfies the equation $m^2+2m$ . Since there is only one value that can satisfy this equation that is 2.
