7x2 - 19xy + 35y2
To factor this, we would need to find two terms which add to make negative 19 and multiply to make 7 * 35 (which is 245). Unfortunately, no such numbers exist. The largest positive product of two numbers that add to make -19 would be -9 * -10, or 90. That's nowhere near big enough reach a product of 245, which tells us that we can't factor it.

How do you factor x cubed plus 9x squared plus 2x plus 18?
Since the problem has 4 terms, first you factor x cubed plus 9x squared, then you factor 2x plus 18. So when you factor the first two term, you would get x sqaured (x plus 9). Then when you factor the last two terms and you get 2 (x plus 9). Ypure final answer would be (x squared plus 2)(x plus 9)
How do you solve 3.5y2 plus 2.6y-8.2 equals 4y2-6.9y using the quadratic formula?
Multiply each item by 10 to give whole numbers then move items to give ay2+by+c=0 3.5y2+2.6y-8.2=4y2-6.9y multiply by 10 35y2 + 26y - 82 = 40y2 -69y subtract 35y2 from both sides 26y - 82=5y2 -69y subtract 26y from both sides -82 = 5y2 - 95y add 82 to each side 0 = 5y2 - 95y +82 or 5y2 - 95y +82 = 0
