Please solve a4 - 41a2 - 72a + 112 =0I have doubt in this biquadratic..Will please somebody solve this kind of biquadratic equation?????
Dear student just put x = 1 and you get the expression 0 hence (x -1) is a factornow x-1 will completely divide it. hence (x-1) (x^3 +x^2 -40x -112) now cubic polynomial is zero at x = 7hence x-7 is a factor now x^2 + 16 + 8x is remaining = (x+4)^2
Dear studentThis equation is not biquadratic as it is not void of a^1 termKindly check and repostRegards
