Question

x⁷+3x²-7 logx+3ex-9 solutions
​

Answer 1

Answer:

Answer:

x = 1.70 or -1.36

Step-by-step explanation:

According to the question the given quadratic equation is: "3x² - x - 7 = 0.

Now, we have to use Sridhar Acharya formula:

x = [-b+√(b²-4ac)]/2a

Here a = +3, b = -1 and c = -7.

So, x = [−(-1)±√((-1)²−4*(3)*(-7))]/2*a

or, x = [+1+√(1+84)]/2*3

or, x= [+1+√85]/6

or, x = [+1+√85]/6 or [+1-√85]/6

or, x = [+1+9.21]/6 or [+1-9.21]/6

or, x= 10.21/6 or -8.21/6

or, x = 1.70 or -1.36 [Ans]

Therefore, correct upto 2 decimal places the value of x will
