Find the roots of the following factored quadratic equation.<br> y= (2x-9) (7x-4)
Marina86 [1]

Answer:

x = 4.5, 4/7

Step-by-step explanation:

To find the roots of a factored equation you need to set the y value at 0, that way you can solve for x. Once you solve for x you get two quantities, which can be graphed. These two quantities are where the x intercepts are.

HELP NEEDED!!! WILL MARK BRAINLIEST!!!
erma4kov [3.2K]

Answer:

x(x + 1)

Step-by-step explanation:

\frac{2x + 1}{ \frac{1}{x} +  \frac{1}{x + 1}  }

Make denominators same:

\frac{2x + 1}{ \frac{x + 1}{x(x + 1)} +  \frac{x}{(x + 1)}  }

Add the numerators:

\frac{2x + 1}{ \frac{x + 1 + x}{x(x + 1)} }

\frac{2x + 1}{\frac{2x + 1}{x(x + 1)} }

Apply the rule:

\frac{a}{ \frac{b}{c} }  =  \frac{a \times c}{b}

Therefore,

\frac{(2x + 1)\times x(x + 1))}{2x + 1}

Cancel out common factor of 2x+1:

x(x + 1)
