Answer:
x = -11
Step-by-step explanation:
Add 9 to both sides of the equation
3 − 9 = −42
3 − 9 + 9 = −42 + 9
Simplify
Add the numbers
3 = −33
Divide both sides of the equation by the same term
3 = −33
3/3 = −33/3
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
= −11

Step-by-step explanation:
x⁴+3x³-4x²=0
x²(x²+3x-4)=0
x²+3x-4=0
x²+4x-x-4=0
x(x+4)-1(x+4)=0
(x+4)(x-1)=0
x=-4 or 1
x can't be negative
therefore x=1
x+4=1+4=5
