For which value will the zero of ((2m-5)x+10) be (4)?

Answer and explanation

Correct answer: \(m=\frac{5}{4}\)

If \(x=4\) is a zero, substituting \(x=4\) in \((2m-5)x+10\) must give zero. Thus, \(4(2m-5)+10=0\). On simplifying, \(8m-20+10=0\), so \(8m=10\) and hence \(m=\frac{5}{4}\). For \(m=\frac{5}{2}\), the coefficient of \(x\) becomes zero and the expression is \(10\), which has no zero. Exam tip: Substitute the given zero in the polynomial and equate the result to zero.
