Question

Subtract the second polynomial from the first. (7x²-3x+10); (2x² + 6x-8)​

Answer 1

Given,

Polynomials,

$\[7{x^2} - 3x + 10\& 2{x^2} + 6x - 8\]$

Solution,

Subtract the second polynomial from the first,

$\[\begin{array}{l} = 7{x^2} - 3x + 10 - \left( {2{x^2} + 6x - 8} \right)\\ = 5{x^2} - 9x + 18\end{array}\]$

Hence the resultant polynomial is $\[5{x^2} - 9x + 18\]$.
