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

look a the sides they are perpendicular

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

c. 6tan80
