Find the product for these questions:

1. \((2x)(10x)\)

2. \(-3m(m + 8)\)

3. \(4d(2d - 9)\)

4. \((3x + 4)(x - 2)\)

5. \((2y - 1)(4y - 3)\)

1.( 2x ) ( 10x ) = 20 x²
2. -3m( m + 8 ) = -3m² - 24m

4d( 2d -9 ) = 8d² - 36d

( 3x + 4 ) ( x -2 ) = 3x² - 6x + 4x - 8 = 3x² - 2x -8

( 2y -1 ) ( 4y - 3 ) = 8y ² - 6y - 4y + 3 = 8y² -10y +3

Solution 1 : ( 2 x ) ( 10 x )
= 20 x 2 ​
Solution 2 : − 3 m ( m + 8 )
= − 3 m 2 − 24 m ​
Solution 3 : 4 d ( 2 d − 9 )
= 8 d 2 − 36 d ​
Solution 4 : ( 3 x + 4 ) ( x − 2 ) = 3 x 2 − 6 x + 4 x − 8 = 3 x 2 − 2 x − 8 ​ Solution 5 : ( 2 y − 1 ) ( 4 y − 3 ) = 8 y 2 − 6 y − 4 y + 3 = 8 y 2 − 10 y + 3 ​
Note : *Remember this formulas : a ( b + c ) = ( a × b ) + ( a × c ) ( a + b ) ( c + d ) = ( a × c ) + ( a × d ) + ( b × c ) + ( b × d ) *

The products of the expressions are: 1. 20x², 2. -3m² - 24m, 3. 8d² - 36d, 4. 3x² - 2x - 8, and 5. 8y² - 10y + 3.
