x = (3Β±β(9+32))/-8
To solve the quadratic equation -4x^2 - 3x + 2 = 0 using the quadratic formula, we need to identify the coefficients first.
The equation is in the form ax^2 + bx + c = 0, where:
a = -4
b = -3
c = 2
Now, we can apply the quadratic formula:
x = (-b Β± β(b^2 - 4ac)) / 2a
Substituting the values:
x = (β(β3) Β± β((β3)^2 - 4(-4)(2))) / (2(-4))
Simplifying further:
x = (3 Β± β(9 + 32)) / -8
x = (3 Β± β41) / -8
Therefore, the two solutions to the quadratic equation -4x^2 - 3x + 2 = 0 are:
x = (3 + β41) / -8
x = (3 - β41) / -8
To solve the quadratic equation -4x^2 - 3x + 2 = 0 using the quadratic formula, we need to know the values of the coefficients a, b, and c. In this case, a = -4, b = -3, and c = 2.
The quadratic formula is given by:
x = (-b Β± β(b^2 - 4ac)) / (2a)
Plugging in the values of a, b, and c into the formula, we have:
x = (-(-3) Β± β((-3)^2 - 4*(-4)*(2))) / (2*(-4))
x = (3 Β± β(9 + 32)) / (-8)
x = (3 Β± β41) / (-8)
So, the two solutions to the equation -4x^2 - 3x + 2 = 0 are:
x = (3 + β41) / (-8)
x = (3 - β41) / (-8)
