Question

Find the value of the expression below for x=6. x^2-2(x+5)

Answer 1

14

Explanation:

If x = 6, then the equation can be simplified to 6^2 - 2 (x+5).

If you continue simplifying, you'd get 36 - 2 (6 + 5), then 36 - 22, which equals 14.

Answer 2

14

Explanation:

x^2-2(x+5)

Let x=6

6^2 -2(6+5)

We follow PEMDAS, parenthesis first

6^2 -2(11)

Then exponents

36 -2(11)

Then multiply and divide

36 -22

Then add and subtract
