Give the values of a, b, and c from the general form of the equation (2x + 1)(x - 2) = 0.
The general form of a quadratic equation is ax2 + bx + c = 0
Given: (2x + 1)(x - 2) = 0.
Let us write it in the standard form.
2x(x - 2) +1(x - 2) = 0
2x2 - 4x + x - 2=0
2x2 - 3x - 2 = 0
Comparing with the standard form of the quadratic equation ax2 + bx + c = 0, we have
a = 2, b = -3, c = -2
Give the values of a, b, and c from the general form of the equation (2x + 1)(x - 2) = 0.
Summary:
From the general form of the equation (2x + 1)(x - 2) = 0, the values are a = 2, b = -3, c = -2
