Solving Quadratics Using Table and Graph

In the equation y = x² +5x +7, match each coefficient with its correct letter

• a=0, b=5, c=7

• a=1, b=5, c=7

• a=7, b=5, c=1

Find the best fitting quadratic model for the data given.

• y = 1.2x² + 13x + 504.3

• y = 12x² + 13x + 504.3

• y = .12x² + 1.3x + 504.3

Factor using UNFOIL

k² -2k - 24 = 0

• (k+4)(k-6) = 0

• (k+4)(k+6) = 0

• (k+6)(k-1) = 0

• (k-4)(k+6) = 0
