The area of a parallelogram is the same as the area of a square. The base of the parallelogram is twice the length of its height

. The side of the square is 2 less than the height of the parallelogram
Area of a parallelogram: a = base • height
Area of a square: a = (side)2
1. variable h = parallelogram height
2. square area + parallelogram area
3. equation: (h – 2)2 + (2h • h)
Analyze Jasper’s work. What was his mistake?
The variable should be the length of the square.
The areas of the square and parallelogram are equal.
The area of a square is 4(h – 2).
The area of a parallelogram is 2h + h.

How do you find the complete square of a math problem
dolphi86 [110]

Step-by-step explanation:

I am not sure what exactly you mean.

do you mean the complete square of an expression or

term ?

if so, then by multiplying this term by itself, and that means in general, every part is multiplied by every part and the part results are added considering the signs involved.

e.g.

squaring a+b

(a+b)(a+b) = a×a + a×b + b×a + b×b = a² + 2ab + b²

remember that multiplication and addition are commutative (you can flip the right and left sides with each other and still get the same result : a+b = b+a, a×b = b×a).

squaring a-b

(a-b)(a-b) = a×a + a×-b + -b×a + -b×-b = a² - 2ab + b²

remember that

+×- = -×+ = -

-×- = +

+×+ = +

a more complex example ?

squaring a-b+c

(a-b+c)(a-b+c) =

= a×a + a×-b + a×c + -b×a + -b×-b + -b×c + c×a + c×-b + c×c =

= a² - 2ab - 2bc + 2ac + b² + c²
