Answer:
21ax+4a−12
Step-by-step explanation:
It is 2.4 x 2.5 which equals 6 the answer is 6
1. a = 3, b = -6, of the standard form.
Rewrite the equation to the vertex form will solve both 2 and 3:
3x^2 - 6x + 13 = 3(x^2 - 2x) + 13 = 3(x^2 - 2x + 1) + 13 + 3 = 3(x - 1)^2 + 16.
where the vertex (h,k) is (1, 16).
