Problems require expanding expressions in the form (ax^2+bx+c)^2 for multiple cases, including terms with negative coefficients and mixed powers of x. The answer key provides the fully expanded polynomials for each numbered item, demonstrating how to place terms into a box layout, multiply, and combine like powers. The set includes problems 1 through 10 (and a partial 1 through 6 version).",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":20,"@type":76,"position":81},"https://docshare.wps.com/document/exam/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/expanding-square-polynomials-using-the-box-method-expand-each-problem/467192/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/expanding-square-polynomials-using-the-box-method-expand-each-problem/467192.png","ImageObject",300,407,{"name":92,"@type":93},"Ezra","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-29","2026-09-30",true,{"@type":102,"interactionType":103,"userInteractionCount":14},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What is the task in this worksheet?","Question",{"text":112,"@type":113},"Expand each given square polynomial using the box method, producing the fully expanded polynomial form.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"Are negative coefficients included in the problems?",{"text":117,"@type":113},"Yes.
