Question

Solution of quadratic equation by the method of completing squares

X^2-3x-10=0

Plz answer fast...

Answer 1

x² - 3x - 10 = 0

x² - (2)(x)(3/2) +(3/2)² = 10 + (3/2)²

(x - 3/2)² - (3/2)² = 0

(x)(x-3) = 0

x = 0 or x = 3

Answer 2

Answer:x=5 or x=-2

Step-by-step explanation:

x^2-3x-10=0

x^2-5x+2x-10=0

x(x-5)+2(x-5)=0

(x-5)(x+2)=0

Therefore,

x-5=0 or x+2=0

x=5 or x=-2
