Welcome to your Solving Algebraic Equations(Study by Topics Junior Class) NAME EMAIL PHONE NUMBER Find the values of y for which 16y - 5 × 4y + 4= 0 -2, 2 0, 1 -1, 0 1, 4 The largest root of the equation (x - 1)² = 4x - 7 is 4 7 2 6 One of the roots of the equation x² + 9 = 0 is -3 3 -9 none of these The positive root of a equation 4x² + 7x = 1, correct to e decimal places is 10.623 1.062 0.322 0.133 If 5 is subtracted from twice a certain number, the result is the same as adding 8 to the original number. Express this statement as an equation. 2x - 5 = x + 8 2x + 5 = x -8 5 - 2x = x + 8 x - 25 = 8 + x 2(5 - x) + 8 = x Solve the equation 3x + 10 = x² -5 or -2 5 or -2 -5 or 2 5 or 2 If 2x + 1 = 15, then x = 7 8 12 14 16 Solve the equation 2x² - 3x - 27 = 0 3/2, 9 -3, 9/2 -2/3, 9 3, 9/2 If P = R/ R+2 % R+2/ R, where R is a number which is neither 0 nor -2, then P ≤ 0 P > 0 P ≥ 0 P = 1 The roots of the equation ay² + by + c = o are 1/2 and -3. The values of a, b and c are, respectively If 3y + 4 - y/3 = y + 9, then y is 5 3 4 6 The roots of the equation5 + 3y - 2y² = 0 are 5/2, 1 5/2, -1 -5/2, -1 -5/2, 1 If y = 2/3 x + 1 and z = 2/3 y + 1, then the value of z when x = 66 is 61 31/2 31 21 The roots of the equation y + 2√y = 8 are 16, 4 4, 1 4, 2 16, 1 What is the value of 2p + 3q, when p = 4 and q = 5? 23 25 20 30 15 Simplify -4 × -6 × 2 48 24 12 -48 -24 Find the roots of the equation3y² + 25y - 18 = 0 -2, 3 -3, 2 -2/3, 9 -9, 2/3 Find the quadratic equation whose roots are y = 7 and y = -2 y² - 2y + 7 = 0 y² - 5y - 14 = 0 y² + 5y + 14 = 0 y² + 2y - 7 = 0 If the equation px² - 6x + 1 = 0 has equal roots, the value of p is 3 9 4 6 Solve the equation -48 + 11n - 20n + 12 = 0 0 -2 2 -4 4 1 out of 20 Time is Up!
