Answer:
(-2.59 , 0)
Step-by-step explanation:
The parabola is y = 3x² + 7x - 2
Clearly it cuts x axis at 2 points A and B
So, put y = 0
3x² + 7x - 2 =0
on solving this we will get two values of x one for A and other for B
Using quadratic formula,
x = [-7 ± √(49 - 4*3*-2)] / 2*3
solve it to get x = 0.25 and -2.59
As from graph A is negative so A ≡ ( -2.59,0)
