Answer:so multiply 12*2=24 and 24*5=120 Is your answer .
Step-by-step explanation:
f(-2) means replace x in the equation with -2, then solve:
-2^2 +5(-2)
Simplify:
4 + -10
Add:
-6
Answer:
mixed fraction= 4 6/35 . exact form= 146/35
D = 120, there are 2 real roots for F(x)
Step-by-step explanatU
using the
formula D = b^2 - 4ac for discriminant
D = 8^2 - 4*(-7)*2
D = 64 + 56 = 120
