Ax ^{2} +5x+2=0 In the equation above, a is a constant. If the equation has the solutions x=-2x = − 2 and x = − 1 2 , what is the value of a?

Explanation:

The form ax2 + bx + c = 0 is called standard form of a quadratic equation. ... If you don't, you might use the wrong values for a, b, or c, and then the ... 2x2 + 3x – 1 = 0; a = 2, b = 3, c = −1 ... Rewrite the equation 2(x + 3)2 – 5x = 6 in standard form and identify a, b, and c. 2(x + ... Start with an equation of the form x2 + bx + c = 0.
