Do you know how to factor x^2 +7x + 10?
do you know the formula for the sum and product of roots
of a quadratic
Yea
the x = (-b ± √ (b² – 4ac) )/2a one?
You can see that the number in the brackets is the sum of 3 and sqrt(2)
And the last term is the product of those numbers
If you apply sum = -b/a and product = c/a, the roots of that polynomial are 3 and sqrt(2)
So the factorization will be (x- 3)(x - sqrt(2)) = 0
Ohh
