@nova.sat1: #creatorsearchinsights #mathproblems When the SAT asks for missing constants in function products like f(x)⋅g(x), don't spend minutes expanding polynomials and equating coefficients 🛑 Use Desmos regression instead! 1️⃣ Multiply the expressions on line 1 using x 1 and swap = for ~: (x_1 + 3)(7x_1^2 - rx_1 + 63) \sim 7x_1^3 + 189 2️⃣ Give Desmos a set of sample values on line 2: x_1 = [1...10] 3️⃣ Type r on line 3 to instantly reveal r=21!
