Question

_______ is a solution of quadratic equation
${x}^{2} - 3x + 2 = 0$
(a) - 3
(b) 1
(c) 3
(d) - 2​

Answer 1

Answer:

-3 is a solution of quadractic equation .

Answer 2

Answer:

option (b) 1

Step-by-step explanation:

x² - 3x + 2 = 0

splitting middle term

=> x² - (2+1)x + 2 = 0

=> x² - 2x - x + 2 = 0

=> x(x-2) - 1(x-2) = 0

=> (x-2)(x-1) = 0

either (x-2) = 0 .......or....... (x-1) = 0

either (x = 2) .......or.......... (x = 1)

1 and 2 are zeros of this equation
