Question

Which of the following is equivalent to the quadratic equation below after
completing the square?
x2 +10x+5 - 30
O
oo
A. (x+5)2 = 35
B. (x+5)2 = 50
C. (x+10)2 = 50
D. (x+10)2 = 35

Answer 1

Answer:

Step-by-step explanation:

x^2 + 10x + 5 - 30 = 0

x^2 + 10x - 25 = 0

x^2 + 10x = 25

x^2 + 10x + 25 = 25 + 25

(x + 5)^2 = 50 <====

Answer 2

C. (x+10)2 = 50 is the answer.

x^2 + 10x + 5 - 30 = 0

x^2 + 10x - 25 = 0

x^2 + 10x = 25

x^2 + 10x + 25 = 25 + 25

(x + 5)^2 = 50

What defines a quadratic equation?

An equation that contains a term that squares an unknown and does not contain a term that squares it solves x in the quadratic equation x2 + 4x + 4 = 0. If c is equal to 0, which is the equation after adding b to b plus the same non-squared equation, then a quadratic equation is obtained.

                    The quadratic equation is a quadratic polynomial expressed as ax2 + bx + c = 0. Where a is nonzero. Where a, b, and c are constants (also known as coefficients) and x is an unknown variable. You can also learn quadratic equations here.
