Answer 1

Answer:

x= 39

because,

(x-2) (x+3)=84

2x-6= 84

2x=84+6

2x=90

X=90\2

x=45

pls mark me as brainlist answer

Answer 2

Answer:

Factors= (x-9)(x+10)

Zeroes/Roots = 9 ,-10

Step-by-step explanation:

(x-2)(x+3)=84

x²+x-6=84

Transpose 84

x²+x-90=0

x²+10x-9x-90=0

x(x+10)-9(x+10)=0

(x-9)(x+10)=0

Roots of x or zeroes of x are 9,-10
