Question

Find the value of x if x - 6× square root of x + 1 + 10 = 0​

Answer 1

Answer:

the answer is 9

Step-by-step explanation:

√x + √x = 6

2√x = 6

I divide both sides by the coefficient of √x, which is 2

√x = 3

I square both sides

x = 9

Another solution to this question is:

I square both sides..

(√x + √x)² = (6)²

(√x + √x)² = 36

(a + b)² = a² + 2ab + b²

(a - b)² = a² -2ab + b²

(√x)² + 2(√x)(√x) + (√x)² = 36

Therefore, x + 2x + x = 36

4x = 36

I divide both sides by the coefficient of x, which is 4

4x/4 = 36/4

Therefore x = 9
