How do you solve x 2 4?

Explanation:

1. x2+4=0 subtract 4 on both sides to get.
2. x2=−4 Take the square root of both sides to get.
3. x=±2i.

What is the answer to 2x 4 2?

2 x − 4 = 2 2x-4=2 2x−4=2. Add 4 to both sides. Simplify 2 + 4 2+4 2+4 to 6. Divide both sides by 2.

What are the factors of x 2 4x 4?

So the factored form is (x+2)(x+2) or (x+2)2 . Hope this helps!

What is the answer for 2+(2X4)?

The answer for 2+2×4 = 10. I followed PEMDAS to solve this problem. i.e. Parentheses Exponential Multiplication Division Addition Subtraction. First work on items in parentheses. Then Exponents, Multiplications if any. Divisions then additions and subtractions. Greetings: This another case of the orders of operations. 2+ (2×4)=?

What comes first 2×4 or 10?

Order of Operations (think PEMDAS or BEDMAS) says that multiplication (M) comes before addition (A), so multiply 2×4 to get 8, then add that 8 to 2, giving the answer of 10. According to the rules of math you would multiply first: 2+ (2×4)=2+8. Then do addition and subtraction, left to right. So 2+8=10

Is it possible to factor x^x2 + 4 using real number coefficient?

x2 +4 cannot be factored using real number coefficient. Depending on your class, that may be enough of an answer. If you really need to factor completely and are allowed to use complex numbers, you can.

What is 8 ÷2(4) divided by 4 (4)?

Now, do the multiplication and division from left to right. 8 ÷ 2 (4) = 4 (4) = 16. The confusion is caused by the difference between modern and historic interpretations of the order of operations, known as PEMDAS: A similar math problem went viral in 2011, when people couldn’t agree on the answer to 48÷2 (9+3).
