Solve the equation 2a\(^2\) - 3a - 27 = 0
3/2, 9
-2/3, 9
3, 9/2
-3, -9/2
-3, 9/2
Correct answer is E
2a\(^2\) - 3a - 27 = 0
2a\(^2\) - 9a + 6a - 27 = 0
a(2a - 9) + 3(2a - 9) = 0
(a + 3)(2a - 9) = 0
a = -3 or a = \(\frac{9}{2}\)
Find the value of m which makes x\(^2\) + 8 + m a perfect square
2
4
8
12
16
Correct answer is E
x\(^2\) + 8 + m
To make it a perfect square, we add \((\frac{b}{2})^2\)
= \((\frac{8}{2})^2\)
= 16
Solve the equation 7y\(^2\) = 3y
y = 3 or 7
y = 0 or 7
y = 0 or 3/7
y = 0 or 9
y = 0 or 10
Correct answer is C
7y\(^2\) = 3y
7y\(^2\) - 3y = 0
y(7y - 3) = 0
y = 0 or y = \(\frac{3}{7}\)
(2e-1) (e-1)
(e+1) (2e+1)
(2e+3) (e+2)
(2e-3) (e-1)
(e2-3(2e-1)
Correct answer is A
2e\(^2\) - 3e + 1
2e\(^2\) - 2e - e + 1
2e(e - 1) - 1(e - 1)
(2e - 1)(e - 1)
