When you have a problem like this, all you have to do is remember that a minus multiplied by a minus is a positive and a minus multiplied by a positive is negative. Since there are five minus signs, the answer is -p.
It is -p... think about it.... two negative signs equal a positive sign, if there are an odd number of negative sign's the real answer is -p, and if there is an even amount, it means it is positive p. In your situation, there are 5 negative signs, so since 5 is an odd number, the p has to be negative.
The discriminant is b<span>²-4ac We can rewrite x</span>² = 4 to x<span>² + 0x - 4 = 0 So a = 1, b = 0, c = -4 </span>Δ = 0 - 4 * 1 * -4 Δ = 16 The answer is B
