factor 5x^2+30x+45

Solution

factor

5 x^{2} + 30 x + 45

Solution

5 (x + 3)^{2}

Solution steps

5 x^{2} + 30 x + 45

Factor out common term

5 : 5 (x^{2} + 6 x + 9)

= 5 (x^{2} + 6 x + 9)

Factor

x^{2} + 6 x + 9 : (x + 3) (x + 3)

= 5 (x + 3) (x + 3)

Apply exponent rule:

aa = a^{2}

(x + 3) (x + 3) = (x + 3)^{2}

= 5 (x + 3)^{2}
