factor each expression completely. if possible. Just checkin the * Ones
1. x^2+19X+90 *
2. x^2-16X+55 *
3. x^2-^6x-91 *
4. x^2+28x+195 *
Solve each equation

Let us know what answers of yours you want checked. This looks like part of a long homework assignment you want someone else to do for you. We don't do that here.
Here's how you would do one of them:
(2x + 5)^2 = 0
2x +5 = 0
x = ?

1. is correct
2. is correct
3. is (x-13)(x+7)
4. is (x+15)(x+13)
Factor the last (constant) number into integers and see which combinations work. For problems 7,8 and 9, you will hace to factor the coefficient of x^2 also.
For #10, try using 2 and 3 as the a and b coefficients of the x terms and 7 and 5 as the constant terms in
(ax + b)(cx + d)= (ax+5)(bx+7)
One of the 2,3 combinations will work.
