Question

x2+20x+64=0 how to slove this equation

Answer 1

We will use the method of splitting the middle term


x² + 20x + 64

=> x² + 16x + 4x + 64

=> x(x + 16) + 4(x + 16)

=> (x + 16) (x + 4)


To factorise the equation in the form of ax² + bx + c, find two numbers whose sum is b and whose product is equal to ac

Answer 2

x = -4
(or)
x = -16
