Set me to Standard

100

ax² + bx = c

ax² + bx + c = 0

200

x(x+2)= 5

x²+ 2x - 5= 0

300

x(x+1) - 12 = 5

x² + x - 17 = 0

400

(x+4) (x - 5) = 0

x² - x- 20 = 0

500

(2x - 3)(3x - 5) = 3

6x² -19x +12 = 0

a, b, c

100

x² + 2x + 3 = 0

a = 1, b = 2, c = 3

200

-x² + 2x = 0

a = -1, b = 2, c = 0

300

x² - 49 = 0

a = 1, b = 0, c = -49

400

4x² - 3x + 9 = 2x² +7x + 3

a = 2, b = -10,  c= 6

500

2x² = 3x - 8

a = 2,  b = -3, c = 8
