Solution
To find the solutions to the equation 4x^2 - 11x - 3 = 0, we can use the quadratic formula, which is x = [-b ยฑ sqrt(b^2 - 4ac)] / (2a). In this equation, a = 4, b = -11, and c = -3.
First, calculate the value under the square root, which is b^2 - 4ac = (-11)^2 - 44(-3) = 121 + 48 = 169.
Then, calculate the two possible values for x:
x1 = [11 + sqrt(169)] / (24) = [11 + 13] / 8 = 3 x2 = [11 - sqrt(169)] / (24) = [11 - 13] / 8 = -0.25
So, the solutions to the equation are x = 3 and x = -0.25.
