WebApr 17, 2024 · If the roots are #1# and #-5#, then (assuming we want a quadratic in #x#) the quadratic has linear factors #(x-1)# and #(x+5)#. Then in order to get a leading coefficient #3#, just multiply the whole expression by #3#... #0 = 3(x-1)(x+5) = 3(x^2+4x-5) = 3x^2+12x-15# So the required equation is: #3x^2+12x-15 = 0#

WebWhen testing for the roots of D you have (in your example) to try 1, 2, 4, 7, 8, 14, 28, 56 and the computing looks quite heavy. When testing for the roots of B, you have to try 1, 7, 1/2 and 7/2. The problem is that the constant coefficient in D has been multiplied by Y N-1 , adding many unnecessary divisors. WebNov 16, 2024 · Step-by-step explanation: Quadratic Equation If the roots of a quadratic equation are known, we can form the equation as follows: where x1 and x2 are the known roots, and a is the leading coefficient. We are given the roots as x1=1 and x2=-6, and the leading coefficient as a=5, thus: Operating: Simplifying: Multiplying: Advertisement … WebHow to find the leading coefficient of a polynomial given as under: 3x(6x + 1) + 2(x + 3x3) = 6 Solution: Here we have: 3x(6x + 1) + 2(x + 3x3) = 6 18x2 + 3x + 2x + 6x3 = 6 Rearranging and merging the terms: 6x3 + 18x2 + 5x– 6 = Now the highest exponent in the above polynomial is 3, so it is the leading term having the leading coefficient of 6. boulevard cinema df
