Question

Solve the equation 4x2 + 2 = 38 using square roots.

Answer 1

Explanation:

Tiger Algebra gives you not only the answers, but also the complete step by step method for solving your equations 4x^2-2=38 so that you ... Step 2 : Step 3 :Pulling out like terms. 3.1 Pull out like factors : 4x2 - 40 = 4 • (x2 - 10) ... x2 = 10. When two things are equal, their square roots are equal.

Answer 2

The value of x is ±3

Using the expression given:

• 4x² + 2 = 38

We can subtract 2 from both sides to isolate 4x²

4x² + 2 - 2 = 38 - 2

4x² = 36

x² = 36/4

x² = 9

x = ±3
