Question

Solve: x²- 15 x + 50 = 0 by factorization.​

Answer 1

Answer:

²-15+50=0

a = 1

b = -15

c = 50

$x = \frac{−(−15)±(−15)2−4⋅1⋅50}{2.1}$

$x = \frac{15±5}{2}$

$x = \frac{15 - 5}{2}$

$x = 10$

$x = 5$

Answer 2

Answer:

x = 5 or x = 10

Step-by-step Explanations :

x² - 15x + 50 = 0 ----------- ( given quadratic equation )

( We can write -15 as -10 & -5. When add Both the number the sum comes out to be -15)

So our factors are -10 & -5

x² - 10x - 5x + 50 = 0

x × ( x - 10 ) - 5 × ( x - 10 ) = 0

( x - 5 ) = 0 , ( x - 10 ) = 0

x = 5 , x = 10

Hence, x = 5 or x = 10
