The polar form of the equation is -2 cosθ
<u>Explanation:</u>
( x + 1 )² + y² = 1
r² = x² + y²
Use x = r cosθ and y = r sinθ
Substitute these variable in x and y
( r cosθ + 1 )² + ( r sinθ )² = 1²
r² cos²θ + 1 + 2 r cosθ + r² sin²θ = 1
r² ( cos²θ + sin²θ ) + 1 + 2 r cosθ = 1
r² + 1 + 2 r cosθ = 1
r² + 2 r cosθ = 0
r² = -2 r cosθ
r = -2 cosθ
Therefore, the polar form of the equation is -2 cosθ

Answer:
to estimate the result of multiplication (product), round the numbers to some close numbers that you can easily multiply mentally. One method of estimation is to round all factors to the biggest digit (place value) they have.
