Q. Solve the equation for all values of x.−x(x2−1)(49x2−16)=0Answer: x=
Analyze the equation: Analyze the equation -x(x^\(2−1)(49x^2−16) = 0").We have a product of three terms equal to zero. According to the zero product property, if the product of several terms is zero, then at least one of the terms must be zero.
Set each term: Set each term in the product equal to zero and solve for x.First term: −x=0Second term: x2−1=0Third term: 49x2−16=0
Solve first term: Solve the first term −x=0.If −x=0, then x=0.
Solve second term: Solve the second term x2−1=0. Add 1 to both sides: x2=1. Take the square root of both sides: x=±1.
Solve third term: Solve the third term 49x2−16=0. This is a difference of squares, which can be factored as (7x−4)(7x+4)=0. Set each factor equal to zero: 7x−4=0 and 7x+4=0.
Solve 7x−4: Solve 7x−4=0.Add 4 to both sides: 7x=4.Divide both sides by 7: x=74.
Solve 7x+4: Solve 7x+4=0.Subtract 4 from both sides: 7x=−4.Divide both sides by 7: x=−74.
