(x2 + 3x - 1) + (4x2 + 2x+5)

5x ^2 + 5x + 4

Step-by-step explanation:

Combining like terms we have

(1+4)x^2 + (3+2)x + (-1+5)

= 5x^2 + 5x + 4

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.
