Question

x⁴-5x²+=0
what is your answer​

Answer 1

Answer:

Here goes the solution!

y=x⁴-5x²+4

Put y=0 in above equation as

x⁴-5x²+4=0

solve the equation for x by factorization

x⁴-4x²-x²+4=0

x²(x²-4)-1(x²-4)=0

(x²-1)(x²-4)=0

x²-1=0 or x²-4=0

x²=1

x=1 or x²=4

x=1 or x=±2

so x-intercept=1,±2
