Question

`( {x}^(2) - 3x) \sqrt{ {x}^(2) + 5x + 4 } = 0`


​

Answer 1

there is is

Explanation:

for x^2-3x=0

x=0 or x=3

Answer 2

x={-4,-1,0,3}

Explanation:

(x²-3x)√x²+5x+4=0

x(x-3)=0

√x²+5x+4=0

x(x-3)=0

x=0

x-3=0

x=3

√x²+5x+4=0

x²+5x+4=0 (square both sides)

x²+4x+x+4=0

x(x+4)+1(x+4)=0

(x+4)(x+1)=0

x+1=0

x+4=0

x=-1

x=-4
