If two similar polygons have a scale factor of 1, what can you conclude? a. they are sometimes congruent. b. they are always congruent. c. they are never congruent. d. they would only be congruent if they were regular polygons.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
