That's again the derivative at 2, so the answer is A. 4. Hard way:

f(x)=x²

f(2)=4

f(2+h) = (2+h)² = 4 + 4h + h²

f(2+h) - f(2) = 4h + h²

(f(2+h)-f(2))/h = 4 + h

Limit is 4.

Answer: A. 4

Use the quadratic formula to solve the equation.–x2 + 5x = 3

Karo-lina-s [1.5K]

Given the equation - x² + 5x = 3, which can be rewritten as:

- x² + 5x - 3 = 0

where a = -1, b = 5 and c = -3.

Quadratic formula:

$\frac{-b\text{ }\pm\text{ }\sqrt[]{b^2\text{ - 4ac}}}{2a}$

Now, we just replace the values of a, b and c on the equation above.

$\frac{-5\text{ }\pm\text{ }\sqrt[]{5^2\text{ - 4(-1)(3)}}}{2(-1)}$

$\frac{5}{2}\text{ }\pm\text{ }\frac{\sqrt[]{13}}{2}$
