Question

find the roots of ײ-7×+12​

Answer 1

x^2 -4x -3x + 12

x(x-4)-3(x-4)

(x-3) (x-4)

x = 3

x = 4

Answer 2

Question:

${x}^{2} - 7x + 12$

Answer:

By Factorisation method

${x}^{2} - 4x - 3x + 12 \\ \\ \implies \: x(x - 4) - 3(x - 4) \\ \\ \implies \: (x - 3)(x - 4)$

To Find the Roots of the Equation Take

X-3 =0 x-4=0

x=3 x=4

Hence the root of the equation is x=4,3
