Quick Check Solutions Solving Quadratic Equations Target B
1) \( 3x^2 + 10x – 5 = 0 \)
Quadratic Formula: the leading coefficient is greater than 2 and cannot be factored.
2) \( 5(x – 4)^2 + 13 = 38 \)
Square Roots: there is a \( (x – 4)^2 \)
3) \( 6x^2 – 9x = 0 \)
Factoring: A GCF of \( 3x \) can be factored out to eliminate the \( x^2 \)
4) \( x^2 – 12x + 9 = 14 \)
Completing the Square: the leading coefficient is 1 and the coefficient of the x-term is even, and it cannot be factored.
