C=√a²+b. square both sides
c²=a²+b². subtract a² from both sides
c²-a² = b². take the square root of both sides
b=±√c²-a²
but since length can never be negative we consider only the positive root
b=√c²- a²
Answer:
Step-by-step explanation:
The general form of a quadratic equation is often written as ...
ax² +bx +c = 0
The references to "a", "b", and "c" are to the coefficients in this form. Comparing this to your equation ...
x²-3x -2 = 0
we see that the coefficient of x², is 1, so a=1; the coefficient of x is -3, so b=-3, and the constant is -2, so c=-2.
You just multiply 3 by both 15x and -17. None of these choices are correct. The only correct application would be A.
