Question

Adding/subtracting polynomials ​

Answer 1

Answer:

$g(x) - h(x) = { - x}^{4} - 11x$

Step-by-step explanation:

$g(x) = {6x}^{2} - 4x + {3x}^{4}$

$h(x) = {6x}^{2} + 4 {x}^{4} + 7x$

$g(x) - h(x)$

$({6x}^{2} - 4x + {3x}^{4}) - ( {6x}^{2} + 4 {x}^{4} + 7x)$

${6x}^{2} - 4x + {3x}^{4} - {6x}^{2} - 4 {x}^{4} - 7x$

$( {3x}^{4} - {4x}^{4}) + ( {6x}^{2} - 6x {}^{2} ) + ( - 4x - 7x)$

${ - x}^{4} - 11x$
