How do i solve this answer ugh please help

Answer 1

Separate the quadratic functions into two individual function in x which multiply together to equal the original quadratic. 
Eg: x^2-3x-10=0       can be written as (x+2)(x-5)=0
The two solutions for x can then be determined by making each bracket equal to zero.
x+2=0 so x=-2x-5=0 so x=5
