To solve quadratic equations like 3x² + x - 2 = 0, factor the expression by grouping terms: 3x(x + 1) - 2(x + 1) = (3x - 2)(x + 1) = 0, then set each factor equal to zero to find the solutions x = 2/3 and x = -1, which sum to -1/3.

Can You Solve This Before I Do? SAT Challenge?💪🧠#satmath #examHinzugefügt:
Most students waste 30 seconds on this SAT question. Watch this. We have 3x squared plus x minus 2 equals 0. Factor it into 3x times x plus 1 minus 2 times x plus 1. Now pull out the common factor. Set each factor equal to 0. Add the solutions. 2 by 3 minus 1 is just minus 1 by 3.
