Factor the following equations to find the zeros of the equation.
irina1246 [14]

The zeroes of the equation are (1,4)

Step-by-step explanation:

Given equation is:

y = x^2 - 5x + 4

We have to put y=0 in the equation to find zeroes of the equation

x^2-5x+4 = 0\\x^2 - 4x- x +4 = 0\\x(x-4)-1(x-4) = 0\\(x-4)(x-1) = 0\\x - 4 =0 => x = 4\\x-1 = 0 => x = 1

Hence,

The zeroes of the equation are (1,4)

Keywords: Equation, zeroes of an equation

Answer:

\large\boxed{x=\dfrac{23}{33}}

Step-by-step explanation:

\text{Let}\ x=0.\overline{69}\\\\x=0.696969...\qquad\text{multiply both sides by 100}\\\\100x=69.696969...\qquad\text{subtract}\ x\ \text{from}\ 100x:\\\\100x-x=69.696969...-0.696969...\\\\99x=69\qquad\text{divide both sides by 99}\\\\x=\dfrac{69}{99}\\\\x=\dfrac{23}{33}
