To factor the polynomial 25x^2 +15x - 4, find two numbers whose product is _ and whose sum is _.

Compare given polynomial with quadratic polynomial

, we get:

a=25, b=15, c=-4

Step1: find product of a and c which is 25*-4= -100

Step2: find two numbers whose product is ac and sum is b that is product is -100 and sum is 15

We see that 20 and -5 satisfy condition of step2.

Step3: Break middle term of into two parts -100x and +15x then proceed factor by grouping.

Hence final answer is .

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.
