Question

Solve. 2x^2 + 9x = 35

x =5/2 and x = –7

x = 35 and x = 13

x = –5/2 and x = 7

x = –35 and x = –13

Answer 1

Rewrite the problem as\[2x^{2}+9x-35=0\]then use the quadratic formula\[x=\frac{-b\pm\sqrt{b^{2}-4ac}}{2a}\]

Answer 2

Using a=2, b=9, c=-35

Answer 3

\[2x^2+9x-35=0\]
\[2x^2+14x-5x-35=0\]
\[2x(x+7)-5(x+7)=0\]
\[(x+7)(2x-5)=0\]

Answer 4

x=-7, x=5/2

Answer 5

FIne...if you want to factor it :)

Answer 6

I swear I just did this one..
