Complete the square 4x^2 + 15x + 2 .
Enter your answer in the form a(x + u)^2 + v, where a, u, and v are replaced by numbers.
+68 Hi Guest,
Factor out the 4 in 4x^2 + 15x + 2
You should have:
4(x^2 + 15x/4 + 1/2)
Next, add and subtract (15/8)^2
4(x^2+15x/4 + 1/2 + (15/8)^2 - (15/8)^2)
Finally, complete the square:
4((x + 15/8)^2) + 1/2 - (15/8)^2)
Answer is: 4(x + 15/8)^2 - 193/16
A = 4, U = 15/8, V = -193/16
