Step-by-step explanation:
Two zeroes are 35 and −35
So we can write it as, x = 35 and x = −35
we get x−35=0 and x+35=0
Multiply both the factors we get,
x2−35=0
Multiply by 3 we get
3x2−5=0 is the factor of 3x4+6x3−2x2−10x−5
Now divide, 3x4+6x3−2x2−10x−5 by 3x2−5=0 we get,
Quotient is x2+2x+1=0
Compare the equation with quadratic formula,
x2−(Sum of
