Solve (x^2+2xy+y^2)(X+1) Show steps

AleksandrR [38]

Answer:

$\large\boxed{x^3+x^2+2x^2y+2xy+xy^2+y^2}$

Step-by-step explanation:

Use FOIL: (a + b)(c + d) = ac + ad + bc + bd

$(x^2+2xy+y^2)(x+1)\\\\=(x^2)(x)+(x^2)(1)+(2xy)(x)+(2xy)(1)+(y^2)(x)+(y^2)(1)\\\\=x^3+x^2+2x^2y+2xy+xy^2+y^2$

What is the prime factorization for 356

densk [106]

Answer:

2² • 89

The prime factors are: 2 x 2 x 89

or also written as { 2, 2, 89 }

Written in exponential form: 2² x 891

Step-by-step explanation:

56 ÷ 2 = 178 - No remainder! 2 is one of the factors!

178 ÷ 2 = 89 - No remainder! 2 is one of the factors!

89 ÷ 2 = 44.5 - There is a remainder. We can't divide by 2 evenly anymore. Let's try the next prime number

89 ÷ 3 = 29.6667 - This has a remainder. 3 is not a factor.

89 ÷ 5 = 17.8 - This has a remainder. 5 is not a factor.

89 ÷ 7 = 12.7143 - This has a remainder. 7 is not a factor.

Find the midpoint of the line segment defined by the points: (5, 4) and (−2, 1) (2.5, 1.5) (3.5, 2.5) (1.5, 2.5) (3.5, 1.5)

Setler79 [48]

Answer:

$\boxed {\boxed {\sf (1.5 , 2.5)}}$

Step-by-step explanation:

The midpoint is the point that bisects a line segment or divides it into 2 equal halves. The formula is essentially finding the average of the 2 points.

$(\frac {x_1+x_2}{2}, \frac {y_1+ y_2}{2})$

In this formula, (x₁, y₁) and (x₂, y₂) are the 2 endpoints of the line segment. For this problem, these are (5,4 ) and (-2, 1).

x₁= 5
y₁= 4
x₂= -2
y₂= 1

Substitute these values into the formula.

$( \frac {5+ -2}{2}, \frac {4+1}{2})$

Solve the numerators.

5+ -2 = 5-2 = 3
4+1 = 5

$( \frac {3}{2}, \frac{5}{2})$

Convert the fractions to decimals.

$(1.5, 2.5)$

The midpoint of the line segment is (1.5 , 2.5)
