What are the zeros of this polynomial and state their multiplicity at each y=(x-5)(x+2)^2

N76 [4]

Answer:

Step-by-step explanation:

The zeros of a polynomial are the x-intercepts of the function. To find them, we factor the polynomial and set each factor equal to 0.

This polynomial is already factored so set each to 0 and solve for x.

$x-5=0\\x=5\\(x+2)^{2}=0 \\(x+2)=0\\x=-2$

This means x=-2, 5. Each zero or root has a multiplicity - the number of times the factor occurs. This is also known as the exponent of the factor expression.

(x+5) occurs once since it has exponent 1.

$(x+2)^{2}$ occurs twoce since it has exponent 2.

x=5 mult. 1, x=-2 mult. 2

Solve for h in the equation 15-2h=6

GREYUIT [131]

Answer:

h is 4.5

Step-by-step explanation:

$15 - 2h = 6$

make 2h the subject:

$- 2h = 6 - 15 \\ - 2h = - 9$

divide all sides by -2:

$\frac{ - 2h}{ - 2} = \frac{ - 9}{ - 2} \\ \\ h = \frac{9}{2} \\ \\ h = 4.5$
