Sample Questions and Solutions Let’s get a view at some sample questions from the Maths Grade thirteen November 2013 Paper I: Question One (Math) Solve for Variable in the formula: 2x2+5x−3=0 Solution Using the quadratic equation expression, we receive: x equals 2a minus b plus or minus the square root of b2 minus 4ac Substituting a equals 2, b equals 5, and c equals -3, we obtain: x = 2(2) - 5 ± sqrt(5^2 - 4*2*(-3)) Solving, we receive: x=4−5±25+24 x=4−5±49 x equals 4 minus 5 plus or minus 7 Thus, x =rac24 = rac12 or x = -12/4 = -3.

Solution Since \(ABCD\) appears an round rhombus, the total of contrary degrees is \(180^ rc\). Thus: ∠A+∠C=180 ∠B+∠D=180 degrees Supplied that \(ngle A = 60^ rc\) and \(ngle C = 120^ rc\), we can determine \(ngle B\): ∠B=180∘−∠D Since \(ngle A + ngle C = 180^ rc\), we understand that \(ngle D = 60^ rc\). Thus: ∠B=180∘−60∘=120∘ But, we as well know that \(ngle B + ngle D = 180^ rc\), so: ∠B=120 degrees However \(ngle B\) and \(ngle D\) are not the sole angles that total combined to \(180^ rc\). We may also express: ∠A+∠C=60∘+120∘=180∘ This proves that \(ngle B = 120^ rc\) appears accurate. Thus: ∠B=180∘−60∘=120∘ But
