Answer 1

Substitute 3 in the place of X you'll get the answer

Answer 2

Step-by-step explanation:

• First multiply 2x^2 by x you will get 2x write it in numerator
• Next x and 2x should be multiplied
• u will get 2x^2
• 2x^2 and 2x^2 should be subtracted
• while subtraction change the sign now u can cancel it
• next multiply 3 and 2x
• u will get 6x
• -7 & +6 should be subtracted
• change the sign of 6x
• u will get -13x
• multiply -13x by x
• send -1 down
• multiply 3 and -13
• its -39
• subtraction change the sign
• cancel -13 ; different sign subract write greater no. sign
• REMAINDER=38 ; NUMERATOR = 2x - 13
