A quadratic equation is set up in the form of ax² + bx +c
First set equation = to 0
0= x² - 5x - 24
Next plug into quadratic formula( -b Plus or minus the √b²-4ac) ÷ 2a
[10 plus or minus √(25² - 4×1×24)] ÷ 2
Solve for inner parenthesis first
√625- 96 = √529
Now set up two equations
(10 + √529) ÷2 = x = 16.5
(10 - √529) ÷2 = x = -6.5
So therefore x = 16.5 and -6.5
Answer:
for part a i think it is the second one sorry if i do get it wrong and i couldnt answer the last one sorry

Answer
6+x=31 0r 6+ x = <31
Step-by-step explanation:
8x10^5 = 800,000
times 800,000 by 0.5 (or just half it) would equal 400,000, which is translated to 4x10^5
