Step-by-step explanation:
We must rewrite 7x^2 = 9 + x in standard form first: 7x^2 - x - 9 = 0.
The coefficients are 7, -1 and -9, and so the discriminant b^2 - 4ac is
(1)^2 - 4(7)(-9) = 253.
The roots are:
-(-1) ± √253 1 ± √253
x = --------------------- = --------------------
2(7) 14
0.04 Times .100 is 0.004. You’re just moving the 4 over a place value (from hundredths place to thousandths place). Notice that if you did 0.04 times 100 you would get 4. Essentially you’re just moving the 4 to different places and adding zeros.
