questions and show your work. When you are finished‚ submit this assignment to your teacher through the appropriate dropbox basket. (3 pts) 1.) Factor 100x^2 – 49 to factor‚ use the difference of squares formula‚ because both the terms are perfect squares the difference of squares formula is a^2 – b^2 = (a-b)(a+b) therefore 100x^2 – 49 = (10x)^2 – 7^2 = (10x – 7)(10x +7) (5 pts) 2.) Solve x^2 – 11x = -30 (x^2 – 11x) + 30 = -30 +30 x^2 – 11x +30 = 0 Reorder the terms: 30 + 11x
