Answer 1

Answer:

x2-2x-35=0

x2-7x+5x-35=0

x(x-7)+5(x-7)=0

(x-7)(x+5)=0

x-7=0 or x+5=0

x=7 or x=-5

Check: x=7 ,LHS = 49-14-35

=0 =RHS

x=-5, LHS = 25+10-35

=0=RHS

Ans: x=7 or x=-5

Answer 2

Answer:

A=5 and B=7

Step-by-step explanation:

x²-2x-35 = (x+A) (x-B)

x²-7x+5x-35= (x+A) (x-B)

x(x-7)+5(x-7)=(x+A)(x-B)

(x+5)(x-7)=(x+A)(x-B)

Thus A=5 and B=7
