Answer:
The equation has two rational solutions
Step-by-step explanation:
6x² - 7x - 5 = 0
(3x - 5)( 2x + 1) = 0
3x - 5 = 0 ⇒ 3x = 5 ⇒ x = 5/3 (rational number)
2x + 1 = 0 ⇒ 2x = -1 ⇒ x = -1/2 (rational number)
The equation has two rational solutions
two rational solutions!!
this is because
6x^2 -7x - 5 = 0
factorising this we get:
6x^2 +3x - 10x - 5 = 0
3x(2x+1) -5 (2x+1)
(3x-5) (2x+1) = 0
solve
3x-5 = 0
3x = 5
x = 5/3
2x+1 = 0
2x = -1
x = -1/2
this is because
6x^2 -7x - 5 = 0
factorising this we get:
6x^2 +3x - 10x - 5 = 0
3x(2x+1) -5 (2x+1)
(3x-5) (2x+1) = 0
solve
3x-5 = 0
3x = 5
x = 5/3
2x+1 = 0
2x = -1
x = -1/2
