Question

1) examine (x+2) is a factor of ( x2+5x2+5x+6) or not..
2) Solve ✓(6-3)³ + (5-1)²
3) Solve 2(6+5)-4(-5+1)
4) Simplify ½[-5(-5-5)+(-4)(-5-7)+4(7+5)]​

Answer 1

2) ✓(6-3)³ + (5-1)² = √ 9+16= √25 = 5

3) 2(6+5)-4(-5+1) = 22+ 16 = 38

4) ½[-5(-5-5)+(-4)(-5-7)+4(7+5)] = 1/2( 50+48+48) = 146/2

= 73
