Tolong jawabin dong makasihh

1) 8x² + 2x - 10
= ( 2x - 2 )( 4x + 5 )
benar

2) 4x² - 25
= ( 2x - 5 )( 2x + 5 )
benar

3) x² - 4x
= ( x - 2 )( x + 2 )
salah
harusnya
x² - 4x = x ( x - 4 )

4) 2x² - 6x = 2 (x² - 8x )
salah
harusnya
2x² - 6x = 2x ( x - 3 )

jadi yg benar 1 & 2 ( A )

2 dan 4

2.
[tex] {4x - 25 }^{2} = (2x - 5)(2x + 5y \\ {4x}^{2} + 10x - 10x - 25 \\ {4x}^{2} - 25[/tex]
4.
[tex]2( {x}^{2} - 8x) \\ {2x}^{2} - 16[/tex]
