WebSep 16, 2024 · Definition 6.2.1: Polar Form of a Complex Number. Let z = a + bi be a complex number. Then the polar form of z is written as z = reiθ where r = √a2 + b2 and θ is the argument of z. When given z = reiθ, the identity eiθ = cosθ + isinθ will convert z back to standard form. Here we think of eiθ as a short cut for cosθ + isinθ. WebFirst, apply the binomial formula. (x+3)² = x²+6x+9. Thus we have. y= -2 (x²+6x+9)-7. Next, distribute the 2 to get. y= -2x²-12x-18-7. Since -18-7=-25 we finally get the standard …
Standard form calculator - Standard form Converter
WebWrite the standard form of a quadratic function: m = ax2 + bx + c. Divide first two terms by a: m = a(x2 + b / ax) + c. Complete the square for the expression with x. Then, add and subtract (b / (2a))2 from the equation: m = a[x2 + x(b / a) + (b / (2a))2– (b / (2a))2] + c. WebExample # 01: Convert the following standard form of the equation into its respective slope intercept form. $$ 2x – 9y = 15 $$.
