Solve the following quadratic equation. Show your solution.

1.3x²-48=0
2.2t²+9=-7t​


Sagot :

Answer:

1.) x = 4

x = - 4

Step-by-step explanation:

1.) 3x² - 48 = 0

Step 1 - Divide both sides by the coefficient of the leading highest term

x² - 16 = 0

Step 2 - Move the constant to the right side and change the sign

x² = 16

Step 3 - Solve quadratic equations using the square root

x = + 16

Step 4 - Solve a solution to x

x = 4
