Answer:

Step-by-step explanation:

<u>The perfect square identity is:</u>

(a + b)² = a² + 2ab + b²

<u>Apply to the given equation to complete the square:</u>

x² + 3x = 6
x² + 2*x*(3/2) + (3/2² = 6 + (3/2)²
(x + 3/2)² = 6 + 9/4
(x + 3/2)² = 8 1/4

Required number is 9/4

Step by step solve for x the following problem... 34 - 5x + 2 (x - 2) = 15

xz_007 [3.2K]

34-5x+2(x-2)=15

34-5x+2(x)(2) (-2)=15

34-5x+2x-4=15

30-3x=15

30-3x-30=15-30

-3x=-15

-3x/-3=-15/-3

x=5
