Question

4x2 - 3x - 1 = 0 ; x=1​

Answer 1

Step-by-step explanation:

• Given 4x² - 3x - 1 = 0

• x = 1

• 4(1)² - 3(1) - 1 = 0

• 4 - 3 - 1 = 0

• 4 - 4 = 0

• LHS = RHS

• Hence x = 1 is root of equation 4x² - 3x - 1 = 0

Answer 2

Answer:

4x^2-3x-1=0

4x^2-4x+x-1=0

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

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

4x+1=0,x-1=0

x=-1/4,x=1 ans.
