Question:

How do I solve for x in the quadratic equation 2(x^2) + 7x - 15 = 0

First, you must factor the quadratic equation: Since 2(x^2) can be factored to x and 2x Thus 2x times some number plus x times a different number must be equal to 7x which we can find by factoring the coefficient -15 The coefficient -15 can be factored 4 different ways 1. 1*(-15) 2.(-1)*15 3. 3*(-5) 4.(-3)*5 Since 2x time 5 plus x times -3 equals 7x The quadratic equation 2(x^2) + 7x - 15 = (2x-3)(x+5) = 0 Since 0 times some number is equal to 0 We can solve the quadratic equation by finding an x that will solve for 0 Thus if 2x-3 = 0 and x+5 = 0 then we can solve algebraically for x 2x - 3 = 0 ---> 2x = 3 ---> x = 3/2 x + 5 = 0 ---> x = -5 Thus 2(x^2) + 7x - 15 = 0 when x is equal to 3/2 and -5

Question:

Which essay should I write A, B, or C?

It depends on the university your applying to. I would recommend that you write all three of them. Some universities may take non-required essays into considering when deciding whether or not to admit you. Furthermore, writing all three essays may allow you to save time in the future if you decide to apply to more universities with different essay requirements.
