I. x2 + 25x + 154 = 0 => x2 + 14x + 11x + 154 = 0 => x(x + 14) + 11(x + 14) = 0 => (x + 11) (x + 14) = 0 => x = -11, -14 II. y2 + 27y + 181 = 0 On solving my qudratic equation formlula we get:- x = (- b ± √(b2 - 4ac)) /2a. Hence, x = y or the relationship cannot be established.
1.55 + 2.05 + 1.5 × 11 – 20% of 10.5 = ?
Determine the simplified value of the given mathematical expression.
√( (664+ √(136+ √(59+ √(21+ √(7+ √81) ) ) ) ) ) = ?
(23 × 8) – (13 × 5) + 67 =? x 6
Simplify the following expression:
Find the value of the expression:
32 + 6 – 5 × [18 + 10 – 3 × (36 – 21)]
20.5 × 36 + 24 × 8 + ?2 = 1954
