Question

(x-2)(42-x)=36+x(39-x) pls answer this step by step​

Answer 1

Step-by-step explanation:

42x-x^2-84+2x=36+39x-x^2

-x^2+x^2+42x+2x-39x=36+84

5x=120

x=120/5

x=24 Answer

Thank me later

Answer 2

Answer:

24

Step-by-step explanation:

(x-2)(42-x)=x(42-x)-2(42-x)

                =42x-x^2-84+2x

                = -x^2+42x+2x-84

                = -x^2+44x-84..............eq(1)

36+x(39-x)= 36+39x-x^2

                 = -x^2+39x+36..............eq(2)

compare (1) and (2)

-x^2+44x-84 = -x^2+39x+36

-x^2+44x-84+x^2-39x-36=0    ( here -x^2+x^2=0)

44x-39x-84-36=0

5x-120=0

5x=120

x=120/5

x=24
