How to solve the equation by completing the square. (not sure what to do with the 2x at the end of the problem)
2x(squared)+6x-14=0

x = 8, or -11.

Step-by-step explanation:

Given:

the given expression.

We need to solve the given expression by completing the square.

Solution:

Rewrite the expression as:

Whole expression divided by 2.

Where:

Solve the given expression by the following formula.

--------------(1)

Substitute b and c value in equation 1.

Add both side of the equation.

Square root of the whole equation.

--------(1)

For positive sign.

Add both side of the equation 1.

x = 8

Similarly for negative sign.

x = -11

Therefore, the value of x = 8, or -11.

answer: i don't understand. what are the options

step-by-step explanation:

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
