- 6x² + 10x + 24
Changing the symbols
• 6x² - 10x - 24 = 0
6x² - 18x + 8x - 24 = 0
6x ( x - 3 ) 8 ( x - 3 ) = 0
( x - 3 ) ( 6x + 8 ) = 0
x = 3
or
x = - 8/6 ➡ - 4/3
So , the value of x is 3 or - 4/3
Answer:
2(3x + 4) (x - 3)
Explanation:
- 6x² + 10x + 24
= 2(3x²) - 10x - 24
= 2(3x²) + 2(-5x) - 24
= 2(3x²) + 2(-5x) + 2(-12)
= 2(3x² - 5x) + 2(-12)
= 2(3x² - 5x - 12
= 2((3x + 4) (x - 3))
= 2(3x + 4) (x - 3)
