Answer:
4x^2 + 8x - 20
Step-by-step explanation:
Amir subtracted a quantity
Let quantity = y
... from the polynomial 3x^2+8x−16
y - (3x^2+8x−16)
and produced the expression x^2−4
= x^2−4
What quantity did Amir subtract?
y - (3x^2+8x−16) = x^2−4
Solving for y;
y = x^2−4 + (3x^2+8x−16)
y = x^2−4 + 3x^2+8x−16
y = 4x^2 + 8x - 20
Quantity subtracted by Amit is [tex]\boldsymbol{2x^2+8x-12}[/tex]
Algebraic Expression
In arithmetic, an expression is a sentence that includes at least two integers (known or unknown) as well as at least [tex]1[/tex] operation.
A quantity is subtracted from the polynomial [tex]3x^2+8x-16[/tex] and the result obtain is the expression [tex]x^2-4[/tex]
Quantity subtracted [tex]=(3x^2+8x-16)-(x^2-4)[/tex]
[tex]=3x^2+8x-16-x^2+4\\=2x^2+8x-12[/tex]
So, quantity subtracted is [tex]\boldsymbol{2x^2+8x-12}[/tex]
