Convert a quadratic from vertex form a(x - h)² + k to standard form ax² + bx + c. Expands the squared binomial.
Convert a quadratic from vertex form a(x - h)² + k to standard form ax² + bx + c. Expands the squared binomial.
The leading coefficient.
The x-coordinate of the vertex.
The y-coordinate of the vertex.
Expands a(x - h)² to a(x² - 2hx + h²) then adds k to get standard form with b = -2ah and c = ah² + k.
How this calculator works
Expands a(x - h)² to a(x² - 2hx + h²) then adds k to get standard form with b = -2ah and c = ah² + k.
