Which equation has the same solution as x^2+8x-33 =0 ?

Mathematics
1 answer:
max2010maxim [7]2 years ago
3 0

Answer:

1) (x+4)2 =49

Step-by-step explanation:

x^2+8x-33 = 0   Factor this equation

(x + 11)(x - 3) = 0     Set each equation equal to 0

x = -11 and 3

Test the first equation to see if it has the same solution

(x+4)2 = 49      Simplify the parentheses

(x+4)(x+4) = 49     FOIL the equation

x^2 + 8x + 16 = 49     Subtract 49 from both sides

x^2 + 8x - 33 = 0       This is the correct solution.

Identify the zeros of the polynomial function N(x)=1/2 (x-1)(x+3).
zhannawk [14.2K]

Answer:

a:x=-3

c:x=1

Step-by-step explanation:

The zeros of a function are the values of x for which the value of the function f(x) becomes zero.

In this problem, we have the following function:

f(x)=\frac{1}{2}(x-1)(x+3)

Here we want to find the zeros of the function, i.e. the values of x for which

f(x)=0

In order to make f(x) equal to zero, either one of the factors (x-1) or (x+3) must be equal to zero.

Therefore, the two zeros can be found by requiring that:

1)

x-1=0\\\rightarrow x=+1

2)

x+3=0\\\rightarrow x=-3

So the correct options are

a:x=-3

c:x=1
