Question

X^2- 20x+75 resole into factors

Answer 1

Answer:  

sum= (-20)

product= 75

Therefore- x^2-20x+75 = 0

              0 = x^2 - 15x - 5x +75

              0 =  x(x-15) - 5(x-15)

              0 = (x-5) (x-15)

              0 = (x-5)                                         0 = (x-15)

              x = 5                                               x = 15

Hope it helps!!
