Solve quadratic equation (x + 3)2 = 49?
Solution:
Quadratic equations are second-degree algebraic expressions and are of the form ax2 + bx + c = 0.
The word "Quadratic" is derived from the word "Quad" which means square.
In other words, a quadratic equation is an “equation of degree 2.”
Given quadratic equation:
(x + 3)2 = 49
Apply square root on both sides
√(x + 3)2 = √ 49
x + 3 = 7
x = 7 - 3
x = 4
Therefore, the solution of the quadratic equation (x + 3)2 = 49 is x = 4
Solve quadratic equation (x + 3)2 = 49?
Summary:
By solving (x + 3)2 = 49, we get x = 4.
