factor 5x^2-40x+80

Solution

factor

5 x^{2} - 40 x + 80

Solution

5 (x - 4)^{2}

Solution steps

5 x^{2} - 40 x + 80

Factor out common term

5 : 5 (x^{2} - 8 x + 16)

= 5 (x^{2} - 8 x + 16)

Factor

x^{2} - 8 x + 16 : (x - 4) (x - 4)

= 5 (x - 4) (x - 4)

Apply exponent rule:

aa = a^{2}

(x - 4) (x - 4) = (x - 4)^{2}

= 5 (x - 4)^{2}
