a^2 - 10ab + 3b^2
*I need a lot of help with this.How do I do this one.?
Try:
(a + r b)(a + s b)
Then:
r + s = -10
r*s = 3
From the first equation:
s = -(10 + r)
Inserting in second expression:
r*(10 + r) = -3 -->
r^2 + 10 r + 3 = 0 --->
r = 5 +/- 2*sqrt[11]
You can use either solution of r, taking the other just amounts to switching r and s.
Typo:
r = -5 +/- 2*sqrt[11]
