Four equivalent forms of a quadratic function are given. Which form displays the zeros of function h?
A. h(x) = -4(x − 2)(x + 2)
B. h(x) = -2(2x2 − 8)
C. h(x) = -4(x2 − 4)
D. h(x) = -4x2 + 16

A. h(x) = -4(x − 2)(x + 2)

Step-by-step explanation:

It's easiest to obtain roots from the factorize form

h(x) = -4(x − 2)(x + 2) = 0

x = 2, -2

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
