Step-by-step explanation:
3x2-3x5i-7ix2x7ix(-5i)
6-15i-14i+35i^2
6-15i-14i+35x(-1)
6-15i-14i-35
From the function y=x^2-4x+7
to complete the square we proceed as follows:
The vertex form is given by:
y=(x-h)^2+k
where (h,k) is the vertex:
thus from the function we shall have:
y=x^2-4x+7
c=(b/2a)²
c=(4/2)²=4
thus adding an subtracting 4 in the expression:
y=x^2-4x+4-4+7
y=(x-2)^2+3
thus the vertex will be:
(2,3)
