factor each expression completely. if possible. Just checkin the * Ones
1. x^2+19X+90 *
2. x^216X+55 *
3. x^2^6x91 *
4. x^2+28x+195 *
5. x^229x+204
6. x^2+3x+154
7. 2x^25x42
8. 3x^213x+12
9. 5x^2+43x18
10. 6x^2+29x+35
Solve each equation
31. x^222x+120=0
32. 4x^2+20x+25=0
33. 4x^2+10x=x^2x+4
34. (x+2)^2+x(x3)=1

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:
32. 4x^2+20x+25=0
(2x + 5)^2 = 0
2x +5 = 0
x = ? 
1. (x+10)(x+9)
2.(x11)(x5)
3.?
4.? 
1. is correct
2. is correct
3. is (x13)(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. 
Thanx
