Question

adding polynomials
the pic is kinda dark..​

Answer 1

Given,

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

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

Therefore,

$h(x) + g(x)$

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

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

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

${7x}^{4} + {12x}^{2} + 3x$
