The answer is (x-y)^2
hope it helps!!!!!!
the formula is
(a-b)^2
and when you expand it, it becomes
a^2-2ab+b^2
12
2 multiplied by 6 is 12 and so 1 multiplied by something is 12
Hope this helps.
A tangent line creates a 90 degree angle with a radius line that touches the tangent Line.
Line BC is a radius that touches the tangent line at point C
The angle created is 90 degrees.
The answer is C. 90 degrees.
<span>2x^2 - 2x - 1 = 0 a = 2, b = -2, c = -1 b^2 - 4ac = (-2)^2 - 4(2)(-1) = 4 + 8 = 12
so the answer is 12
