Question

what is the positive value of x in the following expression?
$2x ^{2} - 7x - 4$
​

Answer 1

Answer:

x = 4

Step-by-step explanation:

Given

2x² - 7x - 4

To solve for x , equate the expression to zero

2x² - 7x - 4 = 0 ← in standard form

(x - 4)(2x + 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

2x + 1 = 0 ⇒ 2x = - 1 ⇒ x = - $\frac{1}{2}$

Thus the positive value of x is x = 4
