The Standard Form for a linear equation in two variables, x and y, is usually given as
Ax + By = C
where, if at all possible, A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1. If we have a linear equation in slope-intercept form,
Answer:
x1=5/2+i
x2=5/2-i
Step-by-step explanation:
x^2-5x+7=0
a=1, b=-5, c=7
x1=(-b+sqrt(b^2-4ac))/2a
x1=(-(-5)+sqrt(5^2 - 4*1*7))/2
x1=(5+sqrt(25-28))/2
x1=(5+sqrt(-4))/2
x1=(5+sqrt(4i^2))/2
x1=(5+2i)/2
x1=5/2+i
x2=(-b-sqrt(b^2-4ac))/2a
x2=(5-2i)/2
x2=5/2-iw
