When simplifying complex numbers and polynomials how are they similar? How are they different?

1 answer:

4 0

They are similar in that you can only combine like terms. They differ in that when you simplify complex numbers, since i² = -1, there are only two types of terms; the real part and the imaginary part. In a polynomial, different powers of the variable are distinct. The field axioms are the same for complex numbers and polynomials.

Solve x2+12x=-11 by completing the square . Which is the the solution set of the equation?

Dmitriy789 [7]

Answer:

{- 11, - 1 }

Step-by-step explanation:

Since the coefficient of the x² term is 1 , to complete the square

add (half the coefficient of the x-term )² to both sides

x² + 2(6)x + 36 = - 11 + 36 ← complete the square on the left side

(x + 6)² = 25 ( take the square root of both sides

$\sqrt{(x+6)^2}$ = ± $\sqrt{25}$

x + 6 = ± 5 ( subtract 6 from both sides )

x = - 6 ± 5

x = - 6 + 5 = - 1 or x = - 6 - 5 = - 11

What are the values of x and y in PQRS? What are PR and SQ?

mamaluj [8]

Step-by-step explanation:

sol;

x+1=y...(1)

3y-7=2x....(2)

or, 3(x+1)-72x [from (1)]

or, 3x+3-7=2x

or, 3x-2x=7-3

x=4

now,

putting the value of x in (1)

y=x+1

=4+1

PR and SQ are the diagonal of PQRS.
