Solution:

1. x^2 + 3 x +2= x^2 + 2 x + x + 2= x(x+2)+1(x+2)=(x+1)(x+2)\\\\ x^2 + 3 x + 2=(x+\frac{3}{2})^2-(\frac{3}{2})^2+2=(x+\frac{3}{2})^2-2.25+2=(x+\frac{3}{2})^2-0.25

2. x^2 + 5 x + 6 =x^2+ 3 x + 2 x+6=x(x+3)+2(x+3)= (x + 2)(x + 3)\\\\ x^2 + 5 x + 6 =(x+\frac{5}{2})^2-(\frac{5}{2})^2+6=(x+\frac{5}{2})^2-6.25+6=(x+\frac{5}{2})^2-0.25

Line 1:  x² + 3 x + 2= (x + 1)(x + 2)= (x + 1.5)² − 0.25 contains three equivalent expressions.

Consider the following expression and determine which statements are true. m+(5n)(9-p)-6-r^2
Fed [463]

Answer:

(B)The expression (5n)(9-p) is the product

(D)The expression 9-p has exactly two terms

Step-by-step explanation:

In the expression;

m+(5n)(9-p)-6-r^2

The coefficient of m is 1, therefore Option A is not true

The product of 5n and 9-p is (5n)(9-p), therefore Option B is true.

The expression 9-p has exactly two terms,9  and p.

Therefore, Options B and D are true.

Can someone help me on this
Cerrena [4.2K]

Answer:

2x+h

Step-by-step explanation:

f(x+h) means that wherever there's an x in the function f(x) we plug in a x+h

we have

(x+h)²+9

Let's start with the numerator

(x+h)²+9-(x²+9)

Distribute the exponent

x²+2xh+h²+9-x²-9

Which gives us

2xh+h²

Divide the whole thing by h to give us

2x+h
