 1.( 2x ) ( 10x ) = 20 x²

2.  -3m( m + 8 ) = -3m² - 24m

3. 4d( 2d -9 ) = 8d² - 36d

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

5. ( 2y -1 ) ( 4y - 3 ) = 8y² - 6y - 4y + 3 = 8y² -10y +3

Solution 1 :
[tex](2x)(10x)[/tex]

[tex]\boxed{= 20x^{2}}[/tex]

Solution 2 :
[tex]-3m(m+8)[/tex]

[tex]\boxed{= -3m^{2} - 24m}[/tex]

Solution 3 :
[tex]4d(2d-9)[/tex]

[tex]\boxed{= 8d^{2} -36d}[/tex]

Solution 4 :
[tex](3x+4)(x-2)[/tex]

[tex]= 3x^{2} - 6x + 4x - 8[/tex]

[tex]\boxed{= 3x^{2} - 2x - 8}[/tex]

Solution 5 :
[tex](2y-1)(4y-3)[/tex]

[tex]= 8y^{2} -6y -4y + 3[/tex]

[tex]\boxed{= 8y^{2} -10y + 3}[/tex]



Note :
Remember this formulas :
[tex]a(b+c) = (a \times b)+(a \times c)[/tex]

[tex](a+b)(c+d)=(a \times c)+(a \times d)+(b \times c)+(b \times d)[/tex]
