**drwls**, Monday, October 29, 2007 at 8:26pmLet 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 = ?

**drwls**, Monday, October 29, 2007 at 8:43pm1. 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.
