solve:
x^2+7x+2=0
My answer:
x= (-7 +/- sqrt (41))/(2)
good one jasmine
To solve the quadratic equation x^2 + 7x + 2 = 0, we can use the quadratic formula. The quadratic formula is given by:
x = (-b +/- √(b^2 - 4ac)) / (2a)
In the equation x^2 + 7x + 2 = 0, we can identify a = 1, b = 7, and c = 2.
Plugging these values into the quadratic formula:
x = (-(7) +/- √((7)^2 - 4(1)(2))) / (2(1))
Simplifying further:
x = (-7 +/- √(49 - 8)) / 2
x = (-7 +/- √41) / 2
Therefore, the two solutions for x are:
x = (-7 + √41) / 2
x = (-7 - √41) / 2
