Answer is 7/12 I know it is because, well I just know it is
(x+b/2a)^2-(b^2-4ac)/2a=0
Step 2:
Re-write the expression:
(x+b/2a)^2=(b^2-4ac)/4a^2
Step 3:
get the square root of both sides:
x+b/2a=sqrt[(b^2-4ac)/4a^2]
Step 4:
Simplifying we get:
x+b/2a=sqrt[b^2-4ac]/2a
Step 5
Make x the subject:
x=-b/2a+/-sqrt[b^2-4ac]/2a
Answer:
x = 5
Step-by-step explanation:
6x - 2(x + 4) = 12 use distributive property
6x + (-2)(x) + (-2)(4) = 12
6x - 2x - 8 = 12 add 8 to both sides
4x = 20 divide both sides by 4
x = 5
(2,0) and (0,10) are order pairs
