Answer:
16
Step-by-step explanation:
f(x) = 2x^2 + 4x + 10
f(-3) = 2(-3)^2 + 4(-3) + 10
f(-3) = 2(9) + (-12) + 10
f(-3) = 18 + (-12) + 10
f(-3) = 16
Answer:
B is the right answer and if you want learn this, than learn algebric expression
Answer:
x²=5-x
x²+x-5=0
1x²+1x²-5=0
[ax²+bx²+c=0]
∆=b²-4ac
∆=1²-4(-5)(1)=1+20=21
x=(-b±√∆)/2a
x=(-1±√21)/2
meaning:
x=(-1+√21)/2 or x=(-1-√21)/2
