Question

Multiply the following binomials and verify the results for the given values,
(1) (2x - 5y) (5x + 2y4); x=2, y=1​

Answer 1

Answer:

step 1 Put values of x and y in the given equation.

= (2×2-5×1) (5×2+2×1×4)

step 2 Now solve the below equation

=(4-5) (10+2×4)

=(-1) (12×4)

=(-1) (48)

step 3 Now combine -1 and 48 by removing brackets

= -1 × 48

= -48 Ans
