You should begin by factorising the numerator and denominator, in order to determine what would go into both parts of the fraction.As you can see, x² and 4x have 'x' in common, and 3x and 12 ha...

First we must remember that a positron is the antiparticle of the electron, meaning that they will both have the same amount of rest energy (0.510999 MeV) however since annihilation produces 2 gamma phot...

Ideally you're aiming to find common factors on both sides of the fraction that cancel out. Firstly we can break this question down into two bits. First bit is factorising 3x^2 -14x+5. Factorizing this wo...

To find the value of a divide the coeffecient of x. Here this would be 6/2 which = 3. If we were to expand (x + 3)^2 + b this would give us:x^2 + 3x +3x + 3^2 +b which simplifies to x^2 + 6x + 3^2 + b. If...

When oxygen is available- aerobic respiration takes place, when oxygen is not available- anaerobic respiration takes place. Pyruvate reacrs differently differently in these two situations.During Aerobic r...
