B²-4ac?
<span>5x²+7x-6 = 0 </span>
<span>the form is ax²+bx+c = 0 </span>
<span>a=5, b=7, c=-6 </span>
<span>The discriminant D = b²-4ac </span>
<span>= 7² - 4(5)(-6) = 49 + 120 </span>
<span>= 169 </span>
Answer: (0,−6),(1,−9/2),(2,−3)
I’m pretty sure these are it!
F(-1)=2 and f(0)=3 are the answers that are not true
31/40
replace 77.5 with 775/10
simplify to get 155/2
divide by 100 to get 31/40
