Answer:

or, 2x-x^2+2x^2=1

or,2x+x^2=1

or,x^2+2x-1=0

or,x^2+x+x-1=0

or,x(x+1)+1(x-1)=0

or,(x+1)(x-1)=0

therefore x=(-1,+1)

Find the slope using the following points: (20,-10)(6,-20)
vagabundo [1.1K]

   \rule{50}{1}\large\blue\textsf{\textbf{\underline{Question:-}}}\rule{50}{1}

    <em>Find the slope using the following points:</em>

<em>         (20, -10) (6, -20)</em>

<em />

<em />\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}

Use the slope formula:-

                    \LARGE\text{$\displaystyle\frac{y_2-y_1}{x_2-x_1}$}

Replace letters with numbers as follows:-

                             \Large\text{$\displaystyle\frac{-20-(-10)}{6-20}$}

On simplification,

                                  \Large\text{$\displaystyle\frac{-20+10}{-14}$}

On further simplification,

                                        \Large\text{$\displaystyle\frac{-10}{-14}$}

Reducing the fraction,

                               \large\text{$\displaystyle\frac{10}{14}$}

               \large\text{$\displaystyle\frac{5}{7}$}\leftarrow\:slope
