Q. Re-write the quadratic function below in Standard Formy=−8(x+4)(x+1)Answer: y=
Expand Quadratic Function: Expand the quadratic function using the distributive property (also known as FOIL - First, Outer, Inner, Last). We have y=−8(x+4)(x+1). First, we'll multiply the terms inside the parentheses. y=−8[(x)(x)+(x)(1)+(4)(x)+(4)(1)]
Combine Like Terms: Continue the expansion by combining like terms.y=−8(x2+x+4x+4)y=−8(x2+5x+4)
Distribute −8: Distribute the −8 across each term inside the parentheses.y=−8(x2)−8(5x)−8(4)y=−8x2−40x−32
Standard Form Expression: Write the final expression in Standard Form, which is Ax2+Bx+C.y=−8x2−40x−32This is the Standard Form of the quadratic function.
