Six hundred and eighty thousand seven hundred and five
x^2 + 10x + 4 = 0
you can use the quadratic formula to solve:
a = 1, b = 10, c = 4
x= −b ± √b^2 −4ac / 2a
x = -10 ± √(10)2 − 4(1)(4) / 2(1)
x = -10 ± √84 / 2
x = -0.42 or -9.58
The area of a square or rectangle is length × width. It changes because the answers to the multiplication problems are different. 3 × 5= 15, while 5 × 5= 25. Because one of the numbers you have to multiply are different in each problem, you'll have a different answer each time.
Answer:
Step-by-step explanation:
9x²+4x-5=0
9x²+9x-5x-5=0
9x(x+1)-5(x+1)=0
(x+1)(9x-5)=0
x=-1,5/9
