Question

X×X+5=30подалуйстаааааа

Answer 1

x*x+5 = 30

x*x = 30-5

x^2 = 25

x1 = 5

x2 = -5

Ответ: -5 ; 5

Answer 2

Sure, let's solve the equation for X:

X×X + 5 = 30

To solve this equation, we need to isolate X on one side of the equation. Follow these steps:

Step 1: Subtract 5 from both sides of the equation to get rid of the constant term on the left side.

X×X = 30 - 5

Step 2: Simplify the right side of the equation.

X×X = 25

Step 3: Take the square root of both sides to solve for X. Remember that we have two possible solutions, one positive and one negative.

√(X×X) = √25

Step 4: Solve for X.

X = ±√25

Step 5: Calculate the positive and negative square roots of 25.

X = ±5

So, the two solutions to the equation are X = 5 and X = -5.
