S.O.S.! Ships navigating the treacherous Bermuda Rectangle are falling prey to bizarre disasters. Factor quadratic expressions to answer the ships’ distress calls and save their stricken crews!
Curriculum-aligned activities
Remove a common factor to leave single brackets. Include more than one factor e.g. 7x² + 14x.
Factorize quadratics and other expressions using the difference of two squares where the first term has a square coefficient other than 1. e.g. (ax)² - (by)² including removing a common factor from each term first.
Factorize quadratics of the form x² + bx + c including those that require manipulation to reduce to this form, including removing a common factor from each term first.
Factorize quadratics of the form ax² + bx + c including those that require manipulation to reduce to this form, including removing a common factor from each term first.
Factorize quadratics and other expressions using the difference of two squares where the coefficient of x² is 1, or where a common factor can be removed to make it 1. e.g. 3x² - 3a².
Solve by first factorising into 2 brackets including equations that require a common factor to be removed first, form x² + bx + c = 0 or px² + pbx + pc = 0.
