Question

please help me solve (x+2) (x+4) (x+6) (x+8) = 105​

Answer 1

After factorising the last equation you will get the values of x

Answer 2

(x+2)(x+4)(x+6)(x+8)=105

x(x+4)+2(x+4)(x+6)(x+8)=105

(x^2+4x+2x+8)x(x+8)+6(x+8)=105

(x^2+6x+8)(x^2+14x+48)=105

x^2(x^2+14x+48)+6x(x^2+14x+48)+8(x^2+14x+48)=105

x^4+20x^3+130x^2+400x+382=105

by factoring method,

105=105

LHS=RHS
