WebAny equation with a factored form of (ax+b) (cx+d) will multiply, by distribution, to get acx^2 + (ad + bc)x + bd. You can then multiply the coefficient of x^2 and the constant (ac*bd) like the instructor suggests. Notice that this is all multiplication a*c*b*d, therefore, using the commutative property, ac*bd=ad*bc. Webfor any quadratic equation like: \purpleD {a}x^2 + \goldD {b}x + \redD {c} = 0 ax2 + bx + c = 0 Example We're given an equation and asked to solve for q q: 0=-7q^2+2q+9 0 = −7q2 + 2q …
