A. Graph these equations on your graphing calculator at the same time.
What happens? Why?
yı = (x-3)(x + 1)
y2 = x2-2x-3
y3 = (x-1)2-4
y4 = x2- 2x + 1

Sundar used linear combination to solve the system of equations shown. he did so by multiplying the first equation by 5 and the second equation by another number to eliminate the y-terms. what number did sundar multiply the second equation by? 2x+9y=41 3x+5y=36
