Question

X-4x²=0 помогититииииии

Answer 1

X-4x²=0
разделим правую левую часть на "-1"
4x²-x=0
вынесем x за скобку 
x(4x-1)=0
произведение равно нулю, если  хотя бы один из множителей равен нулю 
x=0    или   4x-1=0
                   4x=1
                   x=1/4
                   x=0.25
Ответ: {0 ; 0.25}

Answer 2

Solving the Quadratic Equation X-4x²=0

To solve the quadratic equation X-4x²=0, we can use the quadratic formula, which states that for an equation in the form ax² + bx + c = 0, the solutions for x are given by:

x = (-b ± √(b² - 4ac)) / (2a)

In the given equation, a = -4, b = 1, and c = 0. Plugging these values into the quadratic formula, we get:

x = (-1 ± √(1² - 4*(-4)*0)) / (2*(-4))

Simplifying further:

x = (-1 ± √(1 + 0)) / (-8)

x = (-1 ± √1) / (-8)

So, the solutions for x are:

x₁ = (-1 + 1) / (-8) = 0 / (-8) = 0

x₂ = (-1 - 1) / (-8) = -2 / (-8) = 1/4

Therefore, the solutions to the equation X-4x²=0 are x = 0 and x = 1/4.
