dezoksy [38]

Answer:

Infinite solutions.

Step-by-step explanation:

If an equation is an identity, then there will be infinite solutions that the identity will have.

Let, us assume that an identity equation is given by

(a + b)² = a² +2ab + b².......... (1)

Now, putting any real values of a and b the identity will be satisfied.

Therefore, there are infinite solutions for an identity equation. (Answer)

State how many imaginary and real zeros the function has.<br> f(x) = x^4 + 12 x^3 + 37x^2 + 12x + 36

atroni [7]

$x^4+12x^3+37x^2+12x+36=0\\\\x^4+12x^3+36x^2+x^2+12x+36=0\\\\
x^2(x^2+12x+36)+(x^2+12x+36)=0\\\\x^2(x+6)^2+(x+6)^2=0\\\\(x^2+1)(x+6)^2=0\\\\\\x^2+1=0\qquad\vee\qquad x+6=0\qquad\vee\qquad x+6=0\\\\x^2=-1\qquad\vee\qquad x=-6\qquad\vee\qquad x=-6\\\\\boxed{x=i\qquad\vee\qquad x=-i\qquad\vee\qquad x=6\qquad\vee\qquad x=6}$

The function has two imaginary and two real zeros.

Answer:

Choice A

Step-by-step explanation:

(5r - 4)(r² - 6r + 4)

distributive property of multiplication.

5r(r² - 6r + 4) - 4(r² - 6r + 4)

5r³ - 30r² + 20r - 4r² + 24r - 16

group like terms and simplify.

5r³ - 30r² - 4r² + 20r + 24r - 16

5r³ - 34r² + 44r - 16

Choice A.
