The axis of symmetry for a quadratic equation can be found using the formula x = , where a and b are coefficients in the quadrat
ic equation and x represents the values along a vertical line on the coordinate plane. when the equation is solved for a, such that b is the numerator of the resulting fraction, what is the denominator of the fraction?
X = -b/2a <span>multiply both sides by 2a </span> <span>2ax = -b </span> <span>divide both sides by 2x: </span> <span>a = -b/2x to make a positive b in the numerator, make the denominator negative: </span> <span>a = b/-2x </span> <span>answer is b.) -2x </span>
<span>P = mgh </span> <span>divide both sides by mg: </span> <span>P/mg = h
