Step-by-step explanation: Jk, the answer is X = 3 or 1/3 / = Fraction ^ = Power-of * = Multiply Move all the terms to the left then multiply the parentheses: (5x+3) (10-2) - (7x) * (8x) = 0 (50x^2-10x+30x-6)-7x*88x Then multiply variables: (50x^2-10x+30x-6)-56x^=0 Now add all the numbers together: 6x^2+20x-6=0 = 256x Use the following formula: x1=−b−Δ√2a x2=−b+Δ√2a Set up the problem: √ =√256=16 Part 1: -20-16/2x-6 = -36/-12 = 3 Part 2: -20+16/2x-6 = -4/-12 = 1/3
