Answer:
C) 2x^2+7x-4
Step-by-step explanation:
(2x-1)(x+4)=2x^2-x+8x-4=2x^2+7x-4
Answer:
x = 68
Explanation:
⇒ log₈(x - 4) = 2
<u>apply log rules</u>: logₐN = x then N = aˣ
⇒ (x - 4) = 8²
<u><em>simplify</em></u>
⇒ x - 4 = 64
<u><em>add 4 on both sides</em></u>
⇒ x = 64 + 4
<u><em>add the integers</em></u>
⇒ x = 68
Factor the equation. Remember the value should add to the b value and multiply to the c value.
x^2-x-12= 0
(x-4)(x+3)=0
Use the zero product property to find roots
x-4=0
x=4
x+3=0
x=-3
Final answer: x=-3, x=4
