Complete the square of x^2 + 10x -3

ax^2 + bx + c squared form: (x + p)^2 + qDivide b by two where here b=10 and then put this value into where p is in the squared form(x + 5)^2Multiply it outx^2 + 10x + 25Compare this with original equation and adjust it by adding or subtracting a value to get the original equation-3 + 28 = 25so you add 28 to (x + 5)^2Answer: (x+5)^2 + 28
