Answer:
<h3>"
-9x+16"</h3>
Step-by-step explanation:
(-3x + 7) + (-6x + 9)
<em>SIMPLIFY</em><em>:</em>
<em>=</em><em>-</em><em>3</em><em>x</em><em>+</em><em>7</em><em>+</em><em>-</em><em>6</em><em>x</em><em>+</em><em>9</em><em> </em>(add)
<em>ANSWER</em><em>:</em>
<em>=</em><u><em>-</em><em>9</em><em>x</em><em>+</em><em>1</em><em>6</em></u>
Add 3 to both sides so that the equation becomes -2x^2 + 5x + 5 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -5 ± √(5^2 - 4(-2)(5)) ] / ( 2(-2) )
x = [-5 ± √(25 - (-40) ) ] / ( -4 )
x = [-5 ± √(65) ] / ( -4)
x = [-5 ± sqrt(65) ] / ( -4 )
x = 5/4 ± -sqrt(65)/4
The answers are 5/4 + sqrt(65)/4 and 5/4 - sqrt(65)/4..
I’m pretty sure it’s 1. 8:1
