Phương trình (m + 2)x2 – 2mx + 1 = 0 là phương trình bậc hai khi: A. m ≠ 1. B. m ≠ -2. C. m ≠ 0. D. mọi giá trị của m.

B::: m ≠ -2

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

the answer is y = 11.54

hope this : )
