What are the solutions of x2 + 10x + 16 = 0?
1.write the equation in standard form.
2.factor the polynomial.
3.apply the zero product property.
4.solve the resulting equations
x2 + 10x + 16 = 0

(x + 2)(x + 8) = 0

x + 2 = 0 or x + 8 = 0

x = and x=

x= -2 and x= -8

Step-by-step explanation:

Given:

Solution:

1) equation in standard form is  

therefore, is in standard form.

2) factors of the polynomial of the given equation is :

3) zero product property sate that if a.b=0 then either a=0 or b=0

applying this property,

⇒either (x+2)=0 or (x+8)=0

⇒either x= -2 or x= -8

4) solving the equation we get, x= -2 and x= -8

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
