what is the value of the discriminant for the quadratic equation 0 = 2x² + x - 3? discriminant = b² - 4ac\n-25\n-23\n25\n26
Answer
Answer:
C. 25
Explanation:
Step1: Identify coefficients
For the quadratic equation $0 = 2x^{2}+x - 3$, we have $a = 2$, $b = 1$, $c=-3$.
Step2: Substitute into discriminant formula
Substitute $a = 2$, $b = 1$, $c = - 3$ into $b^{2}-4ac$. We get $1^{2}-4\times2\times(-3)$.
Step3: Calculate the result
First, calculate $1^{2}=1$, $4\times2\times(-3)=-24$. Then $1-(-24)=1 + 24=25$.
