Given that α and β are the roots of the equation x² + 3x + 4 = 0, what is the value of ( α + β)²

9

Step-by-step explanation:

sum of roots = α + β

= -b/a

= -3/1 …………………. [b = 3, a = 1]

= -3

(α + β)² = ( -3 )² = -3 × -3 = 9

the image of (6, 9) under a dilation is (4, 6). the scale factor is

b. 2/3

The coordinates of point a right now is (-3,-1) you have to multiply these coordinates by a factor of 2 to get (-6,-2)
