Question

Solve the equation. 4k^2 = 5k

A: {0, - 5/4}

B: {0, 5/4}

C: {0}

D: { 1, 4/5}

Answer 1

The answer is B. Your going to subtract 4k^2 from both sides, which it would be 4k^2-5k=0. Then you going to factor k(4K-5)=0, which k=0 and 4K-5=0 and then k =0 and 4/5

Answer 2

The answer is d. 4(1)^2=5(4/5). 4=4.
