Question

Resolver plis √25-2.5x^2=0

Answer 1

Respuesta:

Simplifying

2.5x2 + -25 = 0

Reorder the terms:

-25 + 2.5x2 = 0

Solving

-25 + 2.5x2 = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '25' to each side of the equation.

-25 + 25 + 2.5x2 = 0 + 25

Combine like terms: -25 + 25 = 0

0 + 2.5x2 = 0 + 25

2.5x2 = 0 + 25

Combine like terms: 0 + 25 = 25

2.5x2 = 25

Divide each side by '2.5'.

x2 = 10

Simplifying

x2 = 10

Take the square root of each side:

x = {-3.16227766, 3.16227766}
