1) Find the equation of the line through the given pair of points in standard form using only integers: (5,1) (-2,7)
2) Use the square root property to find all real or imaginary solutions to the equation: (p-3) exponent 2 = 13
3) Solve the equation by factoring: (X+3) (X-2)= -4

2) = ,     ---> take square root from both sides --->

       = +/- , --->

       = +/- .

      Answer. = +/- .

=========================================================================

3) Solve the equation by factoring: (x+3) (x-2)= -4.

First open parentheses:

= .

Simplify, collect common terms:

= .

Now factor left side:

= (x-1)*(x+2).

Next, solve this equation:

(x-1)*(x+2) = 0.

The solutions are x = 1 and x = -2.

Check yourself these solutions by substituting them into the original equation.

Answer. x = 1 and x = -2.
