Answer:
<em>2x^2 - 7x - 4</em>
Step-by-step 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
<em>hence the expression in standard form is 2x^2 - 7x - 4</em>
Answer:
Step-by-step explanation:
Expanding brackets.
Adding 2m and 6 to both sides.
Combining like terms.
Dividing both sides by 14.
