Question

1. matching. 20 points given the following quadratic equation, identify the a, b, and c: 3x² - 4x = 9 b a c 2. multiple choice 20 points which equation shows the quadratic formula used correctly to solve 5x² + 3x - 4 = 0 for x?

Explanation:

Step1: Rewrite the equation in standard form

The standard form of a quadratic equation is $Ax^{2}+Bx + C=0$. Given $3x^{2}-4x = 9$, we rewrite it as $3x^{2}-4x-9=0$.

Step2: Identify coefficients

For the quadratic equation $3x^{2}-4x - 9=0$, we can see that $A = 3$, $B=-4$, and $C=-9$.

Answer:

B. -4
A. 3
C. -9
