X^2 - 25 = 25 solve for x

Nezavi [6.7K]

Answer:

$\tt x=\pm5\sqrt{2}$

Step-by-step explanation:

$\tt x^2 - 25 = 25$

$\tt x^2-25+25=25+25$ (Add 25 to both sides)

$\tt x^2=50$ ( Take square of both sides)

$\tt x=x=\sqrt{50},\:x=-\sqrt{50}$

$\tt x=\pm5\sqrt{2}$

How is an equation like an expression? How is it different?

morpeh [17]

Answer:

See explanation.

Step-by-step explanation:

An expression is a set of terms that are combined using addition, subtraction, multiplication, or division. The following are examples of expressions:

$2x-1$

$5y+8$

$2$

Note: expressions do not equal anything.

In contrast, equations are expressions that equal at least one term. The following are examples of equations:

$2y-4=26$

$4x-4=0$

$x=10$

$y=x+2$

Note: equations do equal a term, as shown in the examples.
