Answer:
Let x be one of the numbers
then since they differ by 3... Let (x-3) be the 2nd Number
Their product is 88
(x-3)x = 88
x²-3x =88
x² - 3x - 88=0
Solving The quadratic eqn
x=11 or x = -8.
To check this answer
since the Numbers are x and x-3
x= 11
x-3 = 11 - 3 = 8
(x-3)x = 8x11 = 88.
Or When x=-8
(x-3) = -8 - 3 = -11
x= -8
(x-3)x = -8 x - 11 = 88.
Have a great day!
Answer:
First Set: [11, 8], Second Set: [-8, -11]
Step-by-step explanation:
The first number will be x. The second number is x-3. So now make an equation: x(x-3)=88 because their product equals 88. So now solve.
Solving:
[tex](x)(x-3)=88[/tex]
[tex]x^{2}-3x-88=0[/tex]
Now you can factor:
[tex](x-11)(x+8)=0[/tex]
[tex]x=11, x=-8[/tex]
Now plug in each number for x for the following equation:
[tex](x)(x-3)=88[/tex]
[tex](11)(11-3)=88[/tex]
[tex]88=88[/tex]
This is true.
[tex](-8)(-8-3)=88[/tex]
[tex]88=88[/tex]
This is true.
Both are true. So now you have two sets of answers.
Your welcome!
