Q - 25x^2 + 30x + 7
the answer will come
x = (-3+√2)/5 or x = (-3-√2)/5
please tell me correct answer please​

Answer 1

Step-by-step explanation:

Given -

• p(x) = -25x² + 30x + 7

To Find -

• Zeroes of the polynomial

Now,

By using Quadratic formula :-

• x = -b ± √b² - 4ac/2a

→ -(30) ± √(30)² - 4×(-25)×(7)/2×-25

→ -30 ± √900 + 700/-50

→ -30 ± √1600/-50

→ -30 ± 40/-50

Zeroes are -

→ x = -30 - 40/-50

→ -70/-50

→ 7/5

And

→ x = -30 + 40/-50

→ 10/-50

→ -1/5
