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#
