I dont understand this math at all
Answer:
Step-by-step explanation:
To factor the expression you need to know its roots.
First find the discriminant of this quadratic polynomial:
Then the roots of the expression are
Now the factored form is
p = s1 +s2+s3
x^2-3x+10 = -8x+5 +3x+3 +s3
combine like terms
x^2 -3x+10 = 5x+8 +s3
subtract (5x+8) from each side
x^2 -8x +2 =s3
The third sdie is x^2 -8x+2
