Question

Verify the results x= -1 y=2 ( 2x -5y ) ( x - 3y ) ​

Answer 1

Step-by-step explanation:

of x=-1 and y=2

(2(-1) -5(2))((-1)-3(2))

we get

(-2-10)(-1-6)

(-12)(-7)

+84

minus and minus get cancelled...

hope the answer is right and hope you understood the problem...

Answer 2

Answer:

Step-by-step explanation: Given= x=-1, y = 2

(2x - 5y) (x - 3y)

Substituting

= (2×-1-5×2) (-1 - 3×2)

= (-2 -10) (-1 -6)

= (-12) (-7)

= 84
