- a polynomial equation of the second degree is said to be as quadratic equation.
- quadratic:-a function, of the form y=ax²+bx+c.
- Standard form of quadratic equation is ax²- bx+c=0
- where a≠0
⇒ y = -2(x-5)²-4
- now 1st we have to solve (x-5)² by using algebraic identify (a-b)²= a²+b²-2ab here a=x nd b = -5
- (x-5)²
- x²-10x+25
- Now
⇒y = -2(x²-10x+25)-4
- distribution of 2 with bracket
⇒ y= -2x²+20x-50-4
⇒ y= -2x²+20x-54
Hence option A (-2x²+20x-54) is right ans.....
Hope it helps !

Answer:
Value of y = 7
Step-by-step explanation:
By the midpoint theorem of the triangles,
"Segment joining midpoints of the two sides of a triangle is parallel to the third side and measure half the length of the third side."
Therefore, from the figure attached,
In ΔFGH,
J and K are the mid points of the two sides GH and FH.
By theorem, segment JK║GF and m(JK) =
(5y + 3) = 2(2y + 5)
5y + 3 = 4y + 10
5y - 4y = 10 - 3
y = 7
Ok so here's a trick king Henry doesn't usually drink chocolate milk or king Henry dabs under dogs calling mom and here's what it will look like the pic and then u have to convert them so 8 liters converting into blank dL so u put a x over the letter L and u don't see that. u see the big U well that means gram liter and meter so u put a x over top of that and now u want to go to the d so now u go just to the d NOT da and ur gonna scoop when ur done scooping them u put a dot where u ended on top of that letter now u get ur first number or what one u started with so I did 8L so I get 8 and since there is no decimal u put it at the end and now I'll scoop and since ur getting smaller u move the decimal to the left (cause left is less) and u get .8 and that's how u do that if u need help with the other ones just let me know and I'll help u
