Question

Fill in the blank to show what the quadratic expression would look like when factored.(5 points)
x2−3x−10
= ( x−
)( x+
)

3x2−6x+9
= (x2−2x+3)

9x

Answer 1

x^2 − 3x − 10 = (x − 5)(x + 2) (blanks: 5, 2)

3x^2 − 6x + 9 = 3(x^2 − 2x + 3) (blank: 3)

9x^2 − 25 = (3x − 5)(3x + 5) (blanks: 5, 3x)
