factor x^2+3x+2.25

Solution

factor

x^{2} + 3 x + 2.25

Solution

(x + 1.5)^{2}

Solution steps

x^{2} + 3 x + 2.25

Rewrite

x^{2} + 3 x + 2.25

as

x^{2} + 2 x \cdot 1.5 + (2.25)^{2}

= x^{2} + 2 x \cdot 1.5 + (2.25)^{2}

Apply Perfect Square Formula:

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

a = x, b = 1.5

= (x + 1.5)^{2}
