Question

Simplify this 13.) 13y² + 9y + 4y² - 31y

Answer 1

Answer: $17y^2-22y$

Step-by-step explanation:

$13y^2+9y+4y^2-31y$

$\mathrm{Group\:like\:terms}$

$=13y^2+4y^2+9y-31y$

$\mathrm{Add\:similar\:elements:}\:13y^2+4y^2=17y^2$

$=17y^2+9y-31y$

$\mathrm{Add\:similar\:elements:}\:9y-31y=-22y$

$=17y^2-22y$
