Answer:

x=-1 or  x=-2

Step-by-step explanation:

Given Equation:

(x^2+2x)+x+2=0

Solving the like terms:

x^2+2x+x+2=0\\\\x^2+3x+2=0

Solving the quadratic equation using Factorization Method:

x^2+x+2x+2=0

Taking common from the equation to make the factors:

x(x+1)+2(x+1)=0\\\\(x+1)(x+2)=0\\\\x+1=0\\\\x=-1\\\\OR\\\\x+2=0\\\\x=-2

The solution of the equation is:

x=-1 or  x=-2

Simply collect like terms, numbers and or variables that have the same number and type of variable.

For example 15x^2 and 10x^2 are like terms. Circle the sign in front of the term to perform the correct operation.

An abstract sculpture in the form of a triangle has a base 21 meters and a height of 12 meters. Find the are of the triangle.
charle [14.2K]
The area of a triangle could be determined using the following formula
\boxed{a= \frac{1}{2} \times b \times h}

plug in the numbers
a =  \frac{1}{2} \times 21 \times 12
a =  \frac{1}{2} \times 252
a= \frac{252}{2}
a = 126

The area of the triangle is 126 square meters
