Question

solve (2x+3)(x-4)=6​

Answer 1

Answer:

7/3

Step-by-step explanation:

2x +3*x -4= 6

3x -1 = 6

3x = 6+1

x= 6+1/3

x= 7/3

Answer 2

ok let me explain ,

so the question is (2x+3) (x-4) = 6

so, it's ------

2x² - 8x + 3x - 12 = 6

or, 2x² - 5x - 12 - 6 = 0

or, 2x² - 5x - 18 = 0

now you have to use sridhharachayara's formula

if a = 2 b = -5 and c = -18

then use , the two answers will be like ---

• -b + √( b ² - 4ac ) / 2a = ?
• -b - √( b² - 4ac ) / 2a = ?
