( X 2 + 5y ) ( 2y + 4 ) X= 4 Y= 2, Can You Simplify By Using Distributive Property?
Answer:
( X 2 + 5y ) ( 2y + 4 )
= x2 (2y +4 ) + 5y (2y +4)
According to the law of distribution of addition over multiplication;
a ( b+ c) = ab + ac
Solve both the terms of equation by using statute of distribution
= x2( 2y) + 4( x2) + 2y (5y) + 4 (5y)
= 2x2y + 4x2 + 10 y2 + 20 y
Put x= 4 and y= 2 in the equation, we get
= 2(4)2 *2 + 4(4)2 + 10 (2)2 + 20 (2)
= 64 + 64 + 40 + 40
= 208
Simplify: 3 + {4y + 2(x2 + y)} + x2
