Question

factorise:5√5x^2+30x+8√5

Answer 1

x=-4/√5 and x = -2√5/5

Answer 2

Answer:

x = -(2√5)/5  or  -(4√5)/5

Step-by-step explanation:

p(x) = 5√5x² + 30x + √5  

  0 = 5√5x² + 20x + 10x + 8√5  

  0 = 5x(√5x + 4) + 2√5(√5x + 4)  

  0 = (5x + 2√5)(√5x + 4)

5x + 2√5 = 0   and    √5x + 4 = 0

x = -(2√5)/5    and      x = -(4√5)/5
