Question

solve 4x^2-36 using factorization method​

Answer 1

Step-by-step explanation:

4x²-36=0

4(x²-9)=0

4=0 not possible

therefore, x²-9=0

x²=9

x= -+√9

x=3 or x= -3 ans

Answer 2

Step-by-step explanation:

4x²-36

4x²+36=0

(2x)² -6²=0

(2x-6) (2x+6)=0

(2x-6)=0 or (2x+6)=0

2x=6 or 2x= -6

x=6/2 or x=-6/2
