What is 3x^2-2n-5=0
please help me!!!
Answers
It is a quadratic equation in 'x', with 'n' mistakenly typed in the second term..
Although you didn't ask for the solutions to the equation, I'm already here
so I might as well go through it and find them:
3x² - 2x - 5 = 0
In terms of the generic quadratic formula:
A = 3
B = -2
C = -5
Plug those into the quadratic formula, and you discover that
x = -1
and
x = ⁵/₃

Answer:
3x^2 - x - 10 = 0
3x^2 - 6x + 5x - 10 = 0
3x(x - 2) + 5(x - 2) = 0
(3x + 5)(x - 2) = 0
x = -5/3 , 2

Δ = b² - 4.a.c
Δ = -1² - 4 . 3 . -10
Δ = 1 - 4. 3 . -10
Δ = 121
There are 2 real roots.
x = (-b +- √Δ)/2a
x' = (--1 + √121)/2.3
x'' = (--1 - √121)/2.3
x' = 12 / 6
x'' = -10 / 6
x' = 2
x'' = -5/3
