The Standard Form of a Quadratic Equation looks like this:a, b and c are known values. a can't be 0 x is the variable or unknown (we don't know it yet)Here are some examples:2x2 + 5x + 3 = 0 In this one a=2, b=5 and c=3 x2 − 3x = 0 This one is a little ...
It is a Quadratic Equation!Let us solve it using the Quadratic Formula:Where a, b and c are from the Quadratic Equation in "Standard Form": ax2 + bx + c = 0Solve 3x2 - 30x - 12 = 0 Coefficients are:a = 3, b = −30 and c = −12 Quadratic Formula:x = [ −b ±...
.Since equation has rational coefficients, the other root is -2 - iNow, the sum of the roots of the given equation S = (-2 + i) + (-2-i)= -4Product of the roots, P = (-2 + i)(-2- i)= (-2)2-i2=4-(-1)=4+1=5Hence, the required equation is x2 - Sx +P= 0...
