6.12n is the answer for your problem
y=4x²+13x-12
factor function using Vieta's theorem
x1=-4; x2=3/4
y=(x+4)(4x-3)
B
Answer:
<h3>
b=</h3>
Step-by-step explanation:
4b+5=t
First, you must get the variable alone! Substract 5 from both sides!
4b<u>+5=t </u>
-5 -5
The 5 cancels out because 5-5=0
The new equation is 4b=t-5
You must divide by 4 to get the variable alone since your solving for b!
<u>4b=t-5</u>
4 4
b=
This is your answer!
