Explanation:
"assuming you mean to simplify"
4x^2+5x+x^2+3x-6
"we simplify the expression by "color(blue)"collecting like terms"
"like terms are terms which contain the same variable (letter)"
"note that "x^2=x xx x
"and is different to a term only containing x"
rArrcolor(red)(4x^2)color(blue)(+5x)color(red)(+x^2)color(blue)(+3x)-6
"to collect like terms we add the "color(magenta)"coefficients"
"of the numbers in front of the variables"
=(color(red)(4x^2+1x^2))+(color(blue)(5x+3x))-6
=color(red)(5x^2)color(blue)(+8x)-6
You mean:
Explanation:
Since I don't know what to do with it.... I guess:
5x^2+8x-6=0
