Setting up For the prayer hall, the breadth comes out as 12 m and the length as:Solving the hall equation gives x = 12 or x = minus 12.5. The negative value is rejected because:Who are believed to have been the first to solve quadratic equations?Which Greek mathematician found lengths that solve quadratic equations by a geometric approach?The formula now called the quadratic formula was derived in C.E. 1025 by:Al-Khwarizmi, who studied several types of quadratic equations around C.E. 800, was a mathematician from:John and Jivanti had 45 marbles together. After each lost 5, the product of their marbles was 124. This leads Each toy cost 55 minus the number of toys made that day. Total cost 750. The unknown number satisfies:Before deciding whether an equation is quadratic, you often need to:An equation that looks cubic may turn out, after simplifying, to be:The zeroes of the quadratic polynomial and the roots of the matching quadratic equation are:Factorising splits the quadratic into two linear factors; the roots come from setting each factor to:Splitting the middle term to factorise a quadratic was learnt in which class?When a factor is repeated, the root is:Sunita's age satisfies x squared equals 9. Her present age is:Besides factorisation, a quadratic can be solved by the method of:b squared minus 4ac is called the:If the discriminant is zero, the two roots are:A negative discriminant means no real roots because no real number has a negative:A pole must be 7 m farther from gate A than gate B on a circular park of diameter 13 m. The pole goes:Solutions of a word problem should be verified against:
