Question

x2

– 7x + 12 =0 by using quadratic formula. solve​

Answer 1

Answer:

x = 4 and 3

Step-by-step explanation:

Calculate D = (b^2) - 4ac = 49 - 48 = 1

-b = - (-7) = 7

a =1

x = (7±1)/2

so x = 4 and 3

Note for calculating zeros of quadratic equation, we use this formula

x = $\frac{-b \frac{+}{}\sqrt{b^{2} - 4ac } }{2a}$
