Question

Tlong dong bentuk akar pangkat nya gimana ya, butu caraanyaaa

Answer 1

C) 10x² + x - 24
=( 5x + 8)(2x - 3)
cara : 10x² = 5x . 2x
-24 = -8 . 3
8.2x - 3.5x = x

d) 6x² + 19x - 7
=(3x - 1)(2x + 7)
cara 6x² = 3x . 2x
-7 = -1 . 7
-1.2x + 3x.7 = 19x

e) 2x² - 21x + 40
(2x - 5)(x - 8)
cara 2x² = 2x . x
40 = (-5)(-8)
-5.x - 2x.8 = -21x
