Number5and9 because they both are equal
Answer:
Step-by-step explanation:
hello :
5x²+8x-4 quadratic expression when : a = 5 and b=8 and c= -4
∆ = b²-4ac ∆ = 8²-4(5)(-4) = 64 +80 = 144 = 12²
X1 = ( -b -√∆)/2a X1 = (-8-12)/10 = -20/10= -2
X2 =(-b+√∆)/2a X2 = (-8+12)/10 = 4/10 = 2/5
us factorisation : a(X-X1)(X-X2)
5x²+8x-4= 5(x+2)(x-2/5) = (x+2)(5x-2)
you can verify ; (x+2)(5x-2) = 5x²-2x+10x-4 = 5x²+8x-4

Step-by-step explanation:
thank you for your time today
Answer:
<em><u>f ( x ) = x ² − 2 x + 1
-------neither even or odd
</u></em>
<em><u>g ( x ) = x ² + 1
------------- neither even nor odd</u></em>
<em><u>h x = − 2 x + 1--------------odd</u></em>
Step-by-step explanation:
f ( x ) = x ² − 2 x + 1
-------neither even or odd
f(2)=(2)² -2(2)+1
f(2)= 4-4+1=1
f(3)= (3)²-2(3) +1
f(3)=9-6+1=4
g ( x ) = x ² + 1
------------- neither even nor odd
g(2)= (2)² +1= 4+1= 5
g(3)= (3)² +1= 9+1= 10
h x = − 2 x + 1--------------odd
h(2)= -2(2) +1= -4+1= -3
h(3)= -2(3) +1= -6+1= -5
