Answer:
or 
Step-by-step explanation:
Using the zero product property, first step is to set the given equation, 
, to zero. Then factorise the left side.
Thus,
Subtract 2 from both sides
Factorise the left side
Find the solution

Answer:Yesterday, Ron helped his father
Step-by-step explanation:
1a) Possible rational roots will be of the form
±{divisor of 10}/{divisor of 4}
Divisors of 10 are {1, 2, 5, 10}
Divisors of 4 are {1, 2, 4}
Then possible rational roots are
{±1/4, ±1/2, ±1, ±5/4, ±2, ±5/2, ±5, ±10}
1b) Your answer is correct.
2) One additional root will be the conjuate of the given complex root.
5 -3i
3) If one root is 5 -√7, another will be 5 +√7. Then your polynomial is
P(x) = (x -(5 -√7))*(x -(5 +√7)) = (x -5)^2 -(√7)^2
P(x) = x^2 -10x +18
