Rewrite the middle term as the sum of two terms and then factor completely.

25x^2+35x+12

Is the following true or false?

x^2+2x-3=(x+1)(x-3)

Can you show me how to do these two problems?

Thank you for any help you can give me.

If the middle is the sume of 20 x and 15 x ...

25x^2+35x+12

25x^2+20x + 15x+12

5x(5x + 4) + 3(5x+4)

(5x+3)(5x+4)...

does -3 and 1 add to +2?
