Now, in this problem, we need to find the roots of the given equation.
00:04
It's a quadratic equation x square plus 3x minus 5 is equals to 0.
00:11
And we have to use the quadratic formula to find its solutions.
00:15
Okay.
00:16
So, if you recall the standard form of quadratic equation, it is ax square plus bx plus c is equals to 0.
00:26
And its solution is given by the formula x equals to minus b plus minus square root b square minus 4ac divide by 2 times a.
00:40
Now in the given, if we compare this given equation with the standard one, we can say that here a is 1, b is 3 and c is minus 5.
00:51
So just put all these value in this formula to find the roots.
00:54
So x will be equals to minus b.
00:58
We have 3 plus minus square root b square means 9 minus 4 times a is 1 and c is minus 5 divide by 2 times a is 1 here...
