alessandro wrote the quadratic equation -6 = x² + 4x - 1 in standard form. what is the value of c in his new equation?\no c = -6\no c = -1\no c = 5\no c = 7
Answer
Explanation:
Step1: Recall standard - form of quadratic equation
The standard form of a quadratic equation is $ax^{2}+bx + c=0$.
Step2: Rewrite the given equation in standard form
Given $-6=x^{2}+4x - 1$. Move all terms to one side to get $x^{2}+4x-1 + 6=0$, which simplifies to $x^{2}+4x + 5=0$.
Answer:
c = 5
