2x^2 + 5x - 12 = 0
2x^2 + 8x - 3x - 12 = 0
2x(x + 4) - 3(x + 4) = 0
(2x - 3)(x + 4) = 0
2x - 3 = 0 or x + 4 = 0, so:-
solution is 3/2, -4.
Yeah it is already in simplest form
Answer:
The answer is x = 25%
Step-by-step explanation:
84 represents 100% of the questions.
63 represents x% of the correct answers.
x = (63x100)/84
x = 6300/84
x = 75% correct answers.
percentage of the wrong answers:
100% - 75% = 25%
