We can solve this quadratic equation using factorisation method as follows
:x2−5x−36=0
x2+4x−9x−36=0
x(x+4)−9(x+4)=0
(x+4)×(x−9)=0
x+4=0orx−9=0
x=−4orx=9
-2/9 x 4/9 is -8
so the answer is -2/9
The answer would be X= -5
answer: 10/4 reduced is 2.5/1 or 2.5.
work: what we are doing is trying to divide ten into groups of four. how many times does 10 fit into four? well, look at the multiples of four, 4, 8, 12... we can see that 8 fits into ten, but 12 doesn't. that means two whole fours can fit into ten (since 4 x 2 = 8) so we still have a 2 left over from the ten. since 2 is one half of four, we can fit in another .5. so, ten can be fit into 2.5 groups. hope this helps, have a great day!
Answer:
Solution is (35,52)
Step-by-step explanation:
Step 1: Rewrite x+y=87
y= -x+87
Step 2: Substitute y=-x+87 into original equation and solve for x.
x=35
Step 3: Substitute value of x (35) and solve for y.
y=52
