Um, x2+3x-5=0? This is ax2+bx+c where a=1, b=3, and c=-5. The sum of the roots is -b/a so that means the sum of the roots is -3. Also, product of the roots is c/a. That means the product of the roots is -5. -3+(-5)= -8. There you have it.
the sum is -b/a and the product is c/a
parallel
multiply by one if ur looking for the sum and divide by one if look ing for the product, easy
The sum is the total when numbers are added together, the product is the total when they are multiplied.
an + an = 2an; an x an = an + n
find the sum and product of the roots of 8×2+4×+5=0
3x squared - 12x - 24 = 0, and -b/a = sum of the roots, and c/a = product of the roots
-9
It is when the answer, when 2 things are multiplied, is the same as when they are added. For instance, 2*2=2+2
-4,3 are the roots of this equation, so for the values for which the sum of roots is 1 & product is -12
product and sum are both the same.product is what you get when both 19 and 3.6 are added (22.6)sum of equals 2.87 and 3.5 added together (6.37)so answer to question is 22.6 minus 6.37 = 16.23
The way in which numbers are grouped when added or multiplied does not change the sum or product.
