Why do the roots of a quadratic equation have the opposite sign of the factors of a quadratic equation

To find the roots of the quadratic equation we set the factors of the quadratic equation equal to 0.

Step-by-step explanation:

Consider the provided information.

Roots of the equation is x-intercepts or zeros of the given equation.

So, By definition, the value of The y-coordinate is zero for points situated on the x-axis.

Thus, we can find the roots of a quadratic function, by putting f (x) = 0.

Now, let (x-a)(x-b) is the factor of any quadratic equation.

To find the roots of the quadratic function we will put our factor equal to 0.

Now by the zero product property either x-a=0 or x-b=0

then

or

 then

So, we can say that to find the roots of the quadratic equation we set the factors of the quadratic equation equal to 0.

the answer is 14ft

step-by-step explanation:

x is variable or an unknown value to find

example:

2x = 5 which means x = 3
