(5x7)-9 Thisis because product means multiply "Of" mean sa smaller equation. therefor you need the (...) then 9 less than is minus but it has to go after the product since it's subtraction
Answer:
Step 1 : Plug values into the quadratic formula
x = -(-5) +/- √ (-5)^2 - (4)(2)(-3) / (2)(2)
Step 2 : Solve
x = 5 +/- √ 25 + 24 / 4
x = 5 +/- √ 49 / 4
x = 5 +/- 7 / 4
x1 = 5 - 7 / 4 AND x2 = 5 + 7 /4
x1 = -1/2 OR - 0.5
x2 = 3

Second step.
To find this, have all the 'ups' as positives and all the 'downs' as negatives, setting up an equation like this:
7 - 3 + 8 - 10 = 2
