factor x^2-9x+20.25

Solution

factor

x^{2} - 9 x + 20.25

Solution

(x - 4.5)^{2}

Solution steps

x^{2} - 9 x + 20.25

Rewrite

x^{2} - 9 x + 20.25

as

x^{2} - 2 x \cdot 4.5 + (20.25)^{2}

= x^{2} - 2 x \cdot 4.5 + (20.25)^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

a = x, b = 4.5

= (x - 4.5)^{2}
