Answer:

x = 1/2 or x = -4

Step-by-step explanation:

Since the product equals zero, use the zero product rule.

(2x - 1)(x + 4) = 0

2x - 1 = 0 or x + 4 = 0

2x = 1   or   x = -4

x = 1/2 or x = -4

Answer: you have 2 solutions for that equation, 1/2 and -4

Step-by-step explanation:

(2x-1)(x+4)=0

2x^2+8x-x-4=2x^2+7x-4

use the formula for quadratic equations

x₁ and x₂  =-(7 (+-)\sqrt49+32)/4=

we have x1= 1/2 and x 2=4

The value of f(h(2)) =2 and h(f(16))= 14

<h3>What is function?</h3>

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input . Mapping or transformation is used to denote a function in math. These functions are usually denoted by letters . The domain is defined as the set of all the values that the function can input while it can be defined. The range is all the values that come out as the output of the function involved.

given:

f(x)= √x-1 , h(x)= x² + 5

Now,

f(h(2))= f( (2)² +5 )

=f(4+5)

=f(9)

=√9-1

= 3-1

=2

h(f(16)) = h( √16-1)

=h( 4-1)

=h(3)

=3² + 5

=9+5

=14
