Question

Tentukan faktor dari: x2-284=0
10x2-18x=0
x2-2x-35=0
2x2+x-6=0

Answer 1

X² - 284 = 0
x² = 284
x = - √284 atau x = √284
10x² - 18x = 0
2x ( 5x - 9 ) = 0
2x = 0
x = 0 atau 5x - 9 =0  5x = 9 x = 9/5
x² - 2x - 35 = 0
( x - 7 ) ( x + 5 ) = 0
x - 7 =0
x = 7 atau x + 5 = 0 x = -5
2x² + x - 6 = 0
( 2x - 3 ) ( x - 2 ) = 0
2x - 3 = 0
2x = 3
x = 3/2 atau x - 2 = 0 x = 2
