Question

plz solve it question5​

Answer 1

Step-by-step explanation:

i think the question was printed wrong because 25*7=175

but 175=35*5

but in the middle he gave +30 which is not possible with both plus signs

so the question must be 25x^2-30x-7=0

I guess....

I hope it helps you........

Answer 2

Quadratic formula = b^2 - 4ac

1. x^2-4x-1

a = 1. ,. b= -4. ,. c = -1

putting values in the above formula

( - 4)^2 - 4 × 1 × -1 = 0

16 + 4 = 0

20 > 0

ROOTS EXIST ....

ok srry 5 I haven't seen

5. 25x^2 + 30x +7

a= 25 ,. b = 30. , c = 7

putting values

(30)^2 - 4 × 25 × 7 = 0

900 - 700 = 0

200 = 0

200 < 0

yes , real roots will exist .

please thanks me and brainliest
