Question

Quadratic equation
pls help me to answer this​

Answer 1

1.

square root of 361 is 19

x^2-19^2=0

(x+19)(x-19)

No.2 is subtract 784 on both sides and same as no.1

3.

subtract 900 on both sides and end up with x^2=0

4.

subtract 29 on both sides and use quadratic formula

same for 5 and 6

for 7,8,9,10

solve the square bracket first and solve with quadratic formula
