Question

Write the equation in standard form
using factoring.
f(x) = (2x
+
1)(x – 4)

Answer 1

2x^2 - 7x - 4

Explanation:

Given the expression f(x) = (2x+1)(x – 4)

To write it in standard form, we need to factorize it

(2x+1)(x – 4)

= 2x(x) - 2x(4) + x - 4

= 2x^2 - 8x + x - 4

= 2x^2 - 7x - 4

hence the expression in standard form is 2x^2 - 7x - 4
