Divide both sides of the equation by 7 to have 1 as the coefficient of the first term : x 2-(6/7)x-1 = 0 Add 1 to both side of the equation : x 2-(6/7)x = 1 Now the clever bit: Take the coefficient of x , which is 6/7 , divide by two, giving 3/7 , and finally square it giving 9/49
3. (A) = (1+3)^2 = 16 and also (-7+3)^2 = 16 Therefore, the answer is C. My Notebook, the Symbolab way. x² + 6x + 7 = 0. Solving quadratics by factorizing (link to previous post) usually works just fine. Subtract 5 5 from both sides of the equation. b2 − 4(ac) b 2 - 4 ( a c) Substitute in the values of a a, b b, and c c.
